Reason Why Digital Transformation is a Necessary Asset for Business

Leave a Comment / Uncategorized /

We all have studied the Darwinian Theory “Survival of the Fittest” at some point of time in our school days. Well, you must be wondering why did Charles Darwin suddenly flashback into the memories today. This is relatively because of the scenario and the speed at which the business world is getting revolutionized. You cannot operate your business organization on the same principles and pattern but the transition to digital transformation becomes pivotal to survive the cutthroat competition. The digital transformation has literally changed the entire facet of the business operation and allowed the entrepreneurs to accelerate with digitalized technology and offer enhanced customer acquisition and retention. This streamlining technology is applicable to all the various areas of business. In fact, the digital speed is five times faster in comparison to the traditional methods of conducting business. So, if you haven’t shifted your gears yet, it’s high time to embrace digital transformation. Digitalizing the Business Operations One of the visible and far-reaching influences that digital transformation has over business organizations is speeding the pace of business operations with the help of digital tools. You don’t have to put in much effort in applying your brains to prepare the business plans as you can direct your employees in focusing on digital strategic tasks. You get all the facts and figures in hand and also don’t have to invest much of the time in manual works, which proves to be time saving. Now let’s analyze this with an example. Suppose you are transforming the IT department of your organization by bringing automation in the testing process. This will allow the professionals of your company to give more time on testing the more complicated applications accurately without much error. Thus, the human effort is also reduced and it brings more efficiency into the system. Managing the Resources Optimally The Digital Transformation has indeed become one of the most important assets for the business enterprises. It provides them an access to gather huge amount of data and information to gain deeper insights. The enterprise can avail the real-time information with the help of big-data analytics to know how their business assets are performing. This literally assists the entrepreneurs to plan the future strategies and take decisions further up to manage their resources better. Here we can cite the example of Internet of Things technology, which has been a boon as far as the big data analytics, is concerned. The virtually connected devices with the IoT provide deeper insight information on the assets, operations and process. Enhancing the Skills and Knowledge We have witnessed a number of hi-tech technologies making their way out in the middle and this scale is continuously growing. Yes, we talked about IOT playing a vital role in data synchronization, but there are others also contributing significantly in the list and have come in the category of future driving technology. You can certainly say that technologies such as Artificial Intelligence, Augmented and Virtual Reality, Cloud Computing, Blockchain, Machine Learning etc. have really turned the tables in the favour of digital transformation. According to a report, 31% of the enterprises still are not convinced about adopting the digital transformation out of fear and apprehension. But they should shun away the misconceptions and welcome this futuristic technology that will help their employees to enhance their skills and be more productive for the company. Become More Customer-Centric in Approach You must be aware of the fact that today the world population is getting more and more addicted to advanced technologies. We have seen a tremendous increase in the number of Smartphones and other electronic gadgets over the recent few years. So, if you want to engage more audiences and enhance the user experience, then implementing the digital transformation into business operations is the key to success. As we have already indicated previously that digital transformation helps a great deal in getting the real-time information and gathering the customer insights. The instance of the e-commerce platform and their enormous growth is a live example of how the customer data is getting synchronized and used for enticing the users by offering their choices and demands. In addition, you can also maximize the benefits of social media to be familiar with what people are currently looking for and what the latest market trend is. The combination of e-commerce with that of social media platform will provide you a strong base for availing, analyzing and utilizing the information and get the desired result to boost profitability. For example, you can launch a particular product based on the customer demand and which is not readily available in the market. Obviously, the greater insights pave the way for offering an improved customer experience. You can offer personalized products and services, which also act as a promotional strategy for the business. Increasing Collaboration and Empowering the Employees Well, the advantage of integrating the digital transformation in your business model is that it instigates the collaboration across the various departments and also empowers your employee’s productivity. The best example in this category is the introduction of BYOD (Bring Your Own Device) technique, which has been adopted by large number of business enterprises. It allows the employees to work from anywhere irrespective of location to function to the best of their abilities. However, if you want to get the maximum output of increasing collaboration, then there needs to be a strong interaction between the different departments. The work culture of the organization gets much more improved. The employees don’t have to fix a scheduled meeting and then sit down to discuss the further strategy of the project. It saves a lot of time. Instead, they all are connected through a strong network and with digital technologies at stack they can even interact with the third-party applications. The sharing of information becomes more placid and they can also sort out a problem jointly. Growth in Digital Products or Product Engineering The rise of digital transformation has not only enabled the business organizations to

Steps to Optimizing the Performance of the React Native Applications

Leave a Comment / Uncategorized /

React Native developed by Facebook has indeed become one of the most preferred JavaScript library code frameworks for creating cross-platform applications. Although the initial launch was just five years ago in 2013 on GitHub but it has created more buzz in comparison to Xamarin and Ionic. The one aspect that literally goes into the favor of the React Native is that it allows the developers to develop mobile and web applications at a much faster pace. Moreover, you can build both the Android and iOS apps by sharing and reusing the codes easily. Another advantage that React Native offers is that there is not much of a difference between completed apps created using Objective-C or Java and React Native. React Native also enjoys the support of a great network of experienced developers. However, it also has a few drawbacks as well. One of the major pitfalls of React Native is that it has got its limitations and as such it is still on the way to improvement. You won’t find some of the custom modules, which means you have to invest some more time to create your own module. Therefore, we would be readily discussing some of the vital ways using which you can improve the performance of your React Native apps. Before we can shed some light on how to fix the performance based issues related to React Native, you need to understand well that the performance of this JavaScript library depends on the architecture to much extent. The increase in the number of navigation controls, the animation and tabs slows down the speed of the user interface in the application. In addition, during the upgrading the application, the version tends to get changed and it can also become a key bottleneck in the application’s performance. The React Native basically communicates with native thread with the help of a bridge. And the architecture of the React Native can be categorized into two categories namely; the React Native developed on Java, Swift or Objective-C and the native created on JavaScript. So, we can focus on these vital parameters to improve the performance. Reducing the Size of the Application The JavaScript framework apps depend largely on the native components and third-party libraries. The more use of the components enhance the size of the application. Therefore, if you have to reduce the size of the application, you have to use ProGuard and also develop apps of variant sizes for an array of device architecture. In addition, please do focus also on the graphic elements and images. You can also take some other steps to curtail the size such as shifting the components from native to react native, reduce the size of the bridge that JavaScript uses to interact with native. You can also go through the open-source libraries to check its stability before using it. Do not use the main thread to pass the components relying on heavy message queues. Reducing the Size of the Image If you want to optimize the performance of your React Native applications, you also need to necessarily reduce the size of the image apart from lowering the size of the application. You should note that the images tend to consume a large part of the memory. There are many ways to achieve your ends. The first is using the smaller size photos. Secondly, you should give preference to the PNG file format for image uploading in comparison to the widely-used JPG or JPEG format. However, it would be best to convert your image version to WebP format. This is because WebP offers a number of benefits such as increasing the loading speed up to 28% and reducing the binary sizes of iOS and Android by 25%. Apart from that, it also cuts down the CodePush bundle by 66% and makes the transition of the navigator smooth. Image Caching The image caching is regarded as an important step when you are planning to improve the performance of React Native applications. It helps in swifter loading of the images. However, the React Native supports the image caching only for the iOS platform. As far as the Android OS is concerned, you get the assistance of the npm libraries for the image caching, but they do not offer optimum performance. Besides you can also face a few other issues such as failure of libraries for not being able to bring the preloaded images when the page of the app gets refreshed. This is known as cache miss. Another problem that might prop up is performance draining when the cache logic is operating towards the JS side of the application. Bettering the App Release Time Bettering the release time of your React Native application should also be a prime target of the developer. However, this can be a daunting task as you need to check each of the components to improve the performance of the libraries. So, if you want a desirable result here you should focus on the Object.Finalize element, which has been regarded as a key obstructer in decreasing the app performance. Thus, even if you are employing a subtle use of the finalizers, you will have to face the problems related to memory crash or errors, even after having sufficient memory space. The main reason why finalizers become barriers is because they operate on a single thread. So, if there are several finalizers that need to be run, you can simply image how much time they would eat up in this entire process. The Improvement in JSON Data The mobile applications are in search for a load resource getting it from the service or a remote URL with the intention of obtaining the requests to pull the data from the server. The data which they receive from the private or the public API are usually accessed in the form of JSON having some compound nested objects. The performance tends to slow down because the programmers store the same data to get an access to the local

The Comparison Between Node.js and Golang: Which One to Choose?

Leave a Comment / Uncategorized /

Today the mobile and web developers have a wide spectrum of choices when it comes to choosing advanced programming languages. The selection of the languages is not only viable for the front-end developers but the backend developers as well. Speaking of that, we are here to talk about two of the most powerful backend technologies: Node.js and Golang. There’s a lot more confusion about which language should be chosen; which language offers you the best results, cuts down your time, and so on. With that said, why don’t we have a comprehensive comparison of both these languages? Let’s get cracking with the basics first! What is Node.js? Node.js is a server-side runtime environment that is built to fulfill the requirements of highly scalable network applications. Node.js is divided into 2 parts: clustered Node.js and non-cluster Node.js. Talking about its popularity: Node.js is used by at least 30 million websites as of today’s date. Moreover, it is considered to be one of the 6 most commonly used programming and markup languages. It is based upon Google Chrome’s V8 JavaScript engine and it consists of innumerable libraries that help in the development of web applications. It also cuts down the development cost by 58%. The highlight of Node is it’s built on JavaScript which makes it quite simpler for developers to execute both server-side and client-side coding by using one language only. Well, to top it all, Node.js is being used by the top companies like Netflix, Linkedin, Trello, PayPal, Medium, and many more. Top Benefits of Node.js Node.js can be used in backend enhancement and it also boosts the frontend capabilities without having to do more hustle.  Node.js is especially known for its capability because it’s known to be the most favourable platform to build scalable applications.  It can also go well with a microservice architecture by allowing quick integration of new elements of your app. Node.js has got a dynamic community with active code posted on Github. Node.js can improve applications’ performance by 50%. Disadvantages of Node.js Node.js sometimes does not support heavy computational tasks. Its recurrent, backward-incompatible API changes lead to quite extensive code alterations. If you are using Node.js, tackling relational databases causes a lot of hurdles. If you are beginning with Node.js without first going into Javascript, you may suffer conceptual issues. When Should Node.js Be Used? Node.js is the perfect platform for server-side applications that have to deal with multiple requests without putting much burden on node. If you are supposed to develop applications like online games, online messenger, and video chat applications then node should be the top choice for you. What is Golang? Golang, which is also known as Go, is an open-source, statistically typed programming language developed by Google. There are 1.1 million developers who use Go as their primary language. Just like Node js, it is also a cross-platform, multipurpose programming language that is highly recommended for web development. Go is also a structural language that comprises the security and performance benefits of C/C++. It is built on the principle of Python for speed of development due to which it is one of the most preferred programming languages all around the world. Golang is a structurally robust, and efficient concurrent programming language and is mainly known for its garbage collection, memory safety, and dynamic interfaces. Its dynamic features are the reason why it is being used on a high note. Top Benefits of Golang Golang has got a high standard library and efficient packages that help you with simple to use in-built functionalities to work on primitive types.   Golang’s standard library also offers testing support that removes other dependencies. Go makes it easier to manage memory with its garbage collection. It is quite an updated programming language and has a rising skill pool. As Golang has pretty simple-to-use syntax, it is easier for the developers to learn and adopt it.    Some Disadvantages of Golang Go does not support all the generic functions. Go does not have tunable GC as Java. As the language is relatively new in the market, the need to hire developers is not as frequent as others. When Should Golang Be Used? Golang is an ideal platform for the applications that require multithreaded tasks. Also, Golang is the top choice to develop backend applications. Apart from this, as golang is a compiled language, the code that is written is directly translated into the format that the processor understands. Node.js or Golang: Which One is Better? Well, if talking about considering a better language among both of these 2 then it will raise quite a logical argument. Node JS has got a pretty expensive space in the market. Whereas Golang is also topping its game leaving JavaScript behind. So, in a nutshell, both these languages have been gaining popularity as per their characteristics and the benefits they have got to offer. It mainly depends on your requirements as to the languages that are most likely to be helpful for you. Golang vs Node.js: A Detailed Comparison Here begins the detailed comparison between these 2 powerful programming languages: Comparison based on the Level of Maturity We will first compare Golang and Node.js based on their maturity level. When we talk about Go, it is adequately mature and robust although introduced in 2009. On the other hand, Node.js is also showing the same maturity and enjoys the support of the larger audience. But the problem lies with the changing API for which the developers may face issues while writing the Node modules. Assessing on the Performance Basis Node.js basically a JavaScript runtime integrated language and is usually on the slower side when it comes to comparison with Go, the improved compiled language. In fact, Golang performs much better than Node.js, which cannot offer the same optimum service as CPU-bound memory due to JavaScript. So, Go outperforms Node.js on this front but having said that the reality is that both offer more or less the same kinds of server results in the

Top Reasons to Choose Ruby on Rails for Web Development Project

Leave a Comment / Uncategorized /

Let’s face it. You have a plethora of options when it comes to choosing a suitable programming language for the web application development. However, you have to be a cautious selector as the particular choice is for a startup web development project. Precisely speaking, the choice primarily depends on the requirements of the project along with other factors such as the expertise level of the team, availability of the libraries and cost. So, considering these aspects, Ruby on Rails or simply RoR is the optimum choice for Startup Web Development. But before we go into the details and pinpoint the specific reasons for why RoR is regarded as an ideal choice for new ventures web development, let’s quickly have a short glance on what Ruby on Rails is. Ruby on Rails is a cross-platform web development application that is written in Ruby under the MIT License. This is basically an open-source framework based on the MVC (Model View Controller) pattern and is one of the most preferred choices of the web developers today. In fact, RoR is not only popular amongst the startups and small businesses but also attracts the large enterprises. It is a well-established programming language, which has similar in integration with the Perl and Python etc. According to Similar Tech, the recent data shows that Ruby on Rails powers about 3,23,580 websites whereas 1,22,158 websites use its competitor Python. The leading website category, which is dominantly using RoR is Business and Industry (19.5%), followed by Arts and Entertainment (7.7%). The advantages of using Ruby on Rails for web development Some benefits of Ruby on Rails, which makes it a popular choice for web developers worldwide. Ease of Learning and Comprehensible One of the biggest factors that go in the favor of RoR is that the programming language is literally easy to learn, comprehend and read. Not only does it use simple English but also utilizes its own domain-specific language. As such the domain-specific language is a difficult customer to handle but the proficient ROR team has struck a good balance and use this domain specific language only in particular cases. This keeps the programming language on the uncomplicated side. Will Certainly Fit within Your Budget Estimate We already know that Ruby on Rails is an open-source framework programming language. It is absolutely available free of cost, which means that even if you have a tight budget in hand, you can still go with RoR without any second thoughts in mind. And therefore, it is considered the best choice for startups and new business ventures, most of whom are not very financially strong. The advantage that RoR has over other programming languages is it that it is accessible under the MIT License, which is a permissible free software license introduced by the Massachusetts Institute of Technology (MIT). The Support of the Rich Libraries The Ruby on Rails is also blessed to have a rich source of libraries that assist in speeding up the process of web development. According to an estimate, RoR reduces the development time almost by 25 to 50% as compared to other languages. The RoR software has been designed in such a manner that it gives priority to convention rather than configuration. This literally makes the job of the developers easier as they don’t have to think too much while maintaining the flexibility and customization of the framework. In fact, RoR components can be configured as well as reused, which helps in reducing the time of the development. Similarly, there are generators automating the basic CRUD functions. In the Ruby on Rails language, the libraries are usually termed as the gems. You can integrate them with basic functions such as the implementation of the payment feature and authorization. The modules are another vital asset that can be used for arranging the Ruby classes, constants and the methods unifying these into a category or unit. Module writing or class writing is more or less the same thing; the only exception being that module begins with a module keyword and not a class keyword. Known for High Scalability The high scalable feature is also what makes Ruby popular on the cards. It supports the caching activity allowing you to look at the fragment caching within the app coding. In addition, it also makes use of the Redis as the caching storage option. You are also allowed to implement a multi-server automation tool that helps to automate the new application variants and deploy to a location. Now taking of Rails; it lets the developers to use the Chef which is a cloud infrastructure framework and also written in Ruby language. The main function of Chef here is managing the infrastructure dependencies helping to develop the folder structures. Besides that it also updates the system configurations using the minimal commands and bootstrapping the whole system. The scalability of the RoR also enhances in the backdoor activities. It offers a seamless user-experience such as confirming the fresh emails from the new registered users. The background functions are vital to showcase the vitality of the product to the customer. You can achieve this by using Sidekiq or Resque. The Coding is Clean and Clear You might have built the best web application without any errors but you may experience some trouble later on for which you need to be prepared. So, it is the benefit of clean codes in Ruby on Rails that will prove as a savoir. It’s difficult to analyze the starting and the end point of coding in some of programming languages. The result is that you have to start from the scratch to ascertain and fix the issues, which may cost you dearly. However, as said the RoR is an exceptional case which moving the code conventions becomes easier from one developer to another. It is clean and clear and as indicated before quite simple to understand as well. Any developer can use it and you don’t have to commence everything from the beginning. Allows the

Estimating the Cost of MVP Development for a Mobile App

Leave a Comment / Uncategorized /

You might be having a brilliant app idea at the back of your mind that you want to finally execute. But just hold on for a minute and calm down your nerves. Before you implement your plan, think over it again. Are you damn sure that your app idea is 100% unique and authentic? Are you absolutely convinced that your mobile app will receive a grand welcome in the market and that the users will start downloading and installing it as soon as it is unveiled? No, certainly not. Nobody in the world can predict what status your mobile application would hold in the future. So, if you are not prepared to take a risk and rather approach a safer route, then it is highly recommended to opt for building an MVP or the Minimum Viable Product of your app. Of course, it would cost you some additional bucks but you don’t have to launch your app with a stressful mind and perceive which way the wind blows. What is a Minimum Viable Product(MVP)? What is an MVP and why is it so important for your mobile application? A Minimum Viable Product or simply MVP can be defined as a set of most essential and minimum features that allows the development team to check the viability of the product and determine the validity of the idea through customer feedback and application usability. Why is MVP Necessary to Develop? If we go through a few reliable statistics, then it would be known that 74% of the startups fail due to premature business strategy, which is not going for MVP before the app release. Similarly, 29% of the startup fails because of financial crisis. The concept of MVP was introduced in the 2001 and since then its scope and benefits have become much wider. It offers you several advantages such as: Setting the Core Functionalities and App Features to get an early version of the product after viable testing Invite investors and win over stakeholders to invest in your app Allowing to evolve the product through the iterative process MVP helps to be cost-effective It minimizes the risk factor before launching the app Let’s have a quick look at the cost estimation of developing an MVP for some of the most popular and widely used applications in the global scenario. Take such as Twitter. Now, if you ask the price estimate for creating an MVP similar to twitter, then you would have to pay $10.000. Similarly, if you are planning to launch an MVP for an app same as Facebook, be ready to pay $15.000 for its prototype. Please don’t misinterpret it with the cost of developing an entire mobile app; we are only emphasizing on the Minimum Viable Product here. Vital Factors that Determine the Cost of MVP Development The cost of developing a Minimum Viable Product or MVP for a mobile application depends on a number of variable factors. The factors are more or less similar to creating a full-fledged app, which is ready to be launched. In most of the cases, the App Development Companies charge their client based on per hour basis and multiply it with the total number of hours spent on development. The Kind of App The Minimum Viable Product chiefly depends on the complexity of the application idea. If the app idea would be challenging, so would be the MVP. You have to primarily decide what are the most important key features that you want to integrate in the app initially through an MVP. Let’s suppose say you are building an MVP for a cab booking app. Here apart from the registration process, third-party implementation, payment gateway, database encryption and a powerful admin panel becomes necessary to include in the MVP. The best part of the job would be categorizing the app features into three categories like must to included, nice to include and not include at all. You should be able to answer the question as how would your app prove helpful for the end users. Make sure the first version of your MVP is simple having basic features and functionalities, Later on you can go on with collecting the data and more complex versions. The scope of MVP also depends on the business requirements. You need to work on product development and customer development simultaneously. The Cost of MVP Design You also need to consider the cost of MVP design and its difficulty and so it is advisable to plan this important aspect in advance. Here, we are talking about the User Interface. Always note that the first initial design has a separate cost. Try to keep the design simple and straightforward that is easily understandable. In addition, you also have to design an attractive user experience design as well. The main components on which the UX design of the MVP depends are the preparation for the design, the wireframe, the mockup and lastly the interaction within the page. In the first stage, you have to begin with the initial preparation of the design. It would probably include a few meetings and discussions with the team members on how to proceed with the task and then take on the next step, which is wireframe and mockup. The wireframe is the skeleton or the basic structure of the MVP design. Here you prepare a rough layout of the navigation screen and other important elements. You can take the help of tools like Bootstrap for designing the wireframe. The wireframe usually takes around 16 to 20 hours and cost around $400. In the next stage, you proceed with the mockup, which is a kind of prototype and is one of the essential steps of the designing process. Here you present and design the MVP based on the ideas to make the client better understands, on what you are trying to do. If you are familiar with designing tools such as Adobe Photoshop or Corel Draw, then designing the mockup would become rather easier. As far as the time consumption is concerned, it takes around 40 hours and would cost

Xcode 10 : All That You Need to Know

Leave a Comment / Uncategorized /

Merely four days have passed since Apple made the official announcement on the launch of a series of hi-tech gadgets that include three new iPhone models and one Smartwatch series 4. In addition, the tech giant also conducted a specific session known as the Platforms State of the Union, which literally focused on developer’s keynote indulged in Apple Platforms. In fact, Apple also announced about the rollout of Xcode 10. To be precise, this is a comprehensive toolset for the developers that allow them to develop various applications for the iPhone, iPad, Mac, Apple Watch and TV. The major function of the Xcode is bundling the simulator, the Operating System frameworks, and the instruments to create Software Development Kits (SDKs) for watchOS 5, iOS12, macOS 10.14 and TVOS 12. So, let’s get more familiar with Xcode 10 including its distinguished features Xcode 10 is a complete package for the developers that let them build highly functional and responsive applications for the entire Apple platforms. The earlier version Xcode 9.3 included Swift 4.1 and the energy tab in the Organizer Window, Asset catalogs, xccov command line tool, and improved source editor performance etc. However, when we talk about the 10.0 version, it involves some amazing features such as enhanced appearance in new Dark Mode on macOS Mojave, much more improved source code editor simplifying the process of code transformation, and view the transition taking place in source control along with the line. It also focuses on accessing details quickly with respect to differences in upstream coding. The other plus point of availing Xcode 10 is that it allows you to develop your own instrument with the help of customizable idea and data analysis. The Swift programming language proves to be a worthy software compiler and also supports developers in building apps at a much quicker pace. It helps in the generation of small binaries. With Xcode 10, the team bonding and collaboration becomes stronger, securer and testing suites also get accelerated. The Dark Mode While you are coding in Xcode, the macOS Mojave offers a new dark interface and you can shift to the dark mode using system preferences. The idea of introducing the dark mode is to make your work look more attractive. The whole interface gets turned into dark including the icons, the fonts, the contrasting color of the jump bar and others etc. The Xcode powers the developers by providing with robust tools, which makes it easier to build the dark apps for the macOS. In addition, you also get adequate support from the Interface Builder helping to rapidly preview and shift the designs from light mode to dark. You can take the assistance of Asset catalog in Xcode to name your assets and define the colors that are only applicable to your apps. You can also come in or out of the dark mode during the debug process. You can use the controls within Xcode and don’t have to go for altering the system settings. The texts like bold, italic, headings and other formats are rendered immediately in the edit while typing. It takes place in the Markdown files. The Jump Bar makes it possible to rapidly navigate the README.md and documentation files as it is well familiar with the Markdown structure. Instantly Swift Source Code Editor The new version of the Xcode also offers the facility of the fastest source code editor. It makes it the text scrolling more seamless, specifically when involved with the editing the source files. You can design the animations with much ease whether you are folding the code to increase the focus or when the Xcode spots the mistakes and fixes it. The Markdown structure is there to help you out in documentation activity. It is important to note that you have to make employ the command-click for choosing the whole structure and then transform or refactor the various programming languages such as Swift, C, Objective C, C++ etc. Now since Swift is an open-source programming language, the list of transformations becomes bigger and bigger. In fact, the active large swift community also plays an active role in this expansion. If you make any change in the code whether locally or by any other team member in the upstream source repository, it would be highlighted beside each line. This would rather make you aware about the developed conflict upon typing a new line of code as you can click on the red indicator to know about the differences in upstream codes. Debugging the Tools We have already mentioned the fact that Xcode offers the debugging tools that allow you to make a selection between the light and dark mode of the interface. Apart from that, you can also make the change in the facade of the macOS app runtime for which you have to use the command Debug > View Debugging > Appearance menu, the touch bar, the debug bar or the Override Appearance menu. The inspector exhibits the named colors during the view debugging indicating their names and informing if they are system colors or not. The Testing in the Xcode 10 The Xcode 10 helps in conducting a simultaneous and parallel test that helps to reduce the time to run the tests separately. In fact, the parallel tests help a great deal for macOS unit tests and iOS and tvOS unit and user interface testing as well. But if you want to carry out the parallel tests, it would be viable to navigate the scheme editor such as Product > Scheme > Edit Scheme. Then you need to choose the Test action followed by the Info tab. After this, you need to set the next text target by selecting the options. Lastly, choose the option to execute in parallel for macOS or execute in parallel on the simulator for iOS and tvOS. Playground for Machine Learning A model just replicating like Read–Eval–Print Loop (REPL), helps in rerunning the existing playground code immediately. To talk of REPL, it is

O.K. so now that you know that chat-based apps are exceedingly popular, you must have settled your mind and looking forward to building a social messaging app like WhatsApp or WeChat. We will offer you a step by step guide on how to create an app same as WhatsApp or Telegram. Things to Consider Before Developing a Messenger App like WhatsApp It is necessary to consider a few vital aspects before you can begin with building a chat-based app like WhatsApp. You should always launch an MVP of the product so that you can check its feasibility and get the all-important user feedback regarding the app. Then you have to take into account the development team that would be working on building the app. You should hire experienced app developers, designers, testers, project managers and others because your app has to compete with most successful apps. Plan your budget in advance and then hire a proficient App Development Company to cater your services. Always keep in touch with the development team to monitor the progress of the project. The Most Remarkable Features of Messenger App Log-in into the Account Any user using the chat-based app such as WhatsApp has to enter the application by registering his account. As such, one of the easiest methods of signing-in into one’s account is via entering the existing mobile number. Once you provide your mobile number, you get an automatic security code by SMS. This verification code is sent for the security purpose. Once this verification process is completed, it’s time to add the contacts from your phone book list. The longer the contact list of the user is, there are more chances that he would be using your app. However, the best part of this registration process in apps like WhatsApp is that the risk of password getting stolen or misused unlike Facebook it is directly connected with the user’s mobile number, which cannot be hacked. You can also offer the benefit of profile customization where the user can customize his profile so thereby changing their nicknames, the background colors, and patterns, etc. Regarding the time, it would nearly take about 40 hours for developing the front as well as the backend of the app, irrespective of the platform chosen. Adding the Messaging Feature Your next job in hand is to create a viable messaging exchange platform using which the users can start conversing with one another conveniently. Upon taping a button, the user comes across the phone book address and he selects the person with whom he wants to chat. You also have to necessarily provide a group chatting option, which has a particular name or theme of the group. The group has a specific number of people with one or many admins controlling the group activity. This is what we have seen in the WhatsApp. In addition, you can also add another new feature called Broadcast Group where you can send a single message to many individuals simultaneously instantly. The XMPP technology allows users to share the message and facilitates with group conversation the same as the HTTP. It contains a socket, which remains open until the user is logged-in but closes after the message receive or sending. Another notable point to remember is that WhatsApp does not store the message in its server. It only stays active until the server delivers it to the acknowledgment of the receiver. It then gets eliminated from the temporary storage. However, in case you want to store a message on the server, you have to make arrangements for its security. The choice is yours. The customization of the stickers is what can hike the user engagement towards the app. Allow your users to create their own stickers, which indeed has become an important part of the interaction today. The time required to build this feature is 200 hours including 100 hours for front-end and 100 hours for the backend. Push Notifications We are evidently aware that Push Notifications play a significant role in sending important information to your customers. When you are creating an app like WhatsApp, you have to inform your users about two key things; first, when a new message is delivered and secondly when he is added to a specific group. The pop-ups and push notifications carry out this task of sending or receiving messages if the screen is locked. The developers can look to implement the Google Cloud Messaging for Android and Apple Push Notifications for integrating this feature. The total time devoted to

React Native Vs Ionic: The Battle of Two Cross-Platform App Development Frameworks

Leave a Comment / Uncategorized /

The mobile application market is surging up and according to the current statistics; the number of apps has already exceeded 8 million as per the first quarter of 2018. The competition for the mobile app development industry is becoming more challenging and it really has a daunting task to engage customers. Most developers would agree upon the selection of platform or framework plays a vital role in increasing the customer retention and enhancing its popularity. And there is no paucity of choices as far as number of platforms is concerned. If you are planning to develop a cross-platform app, the story there is no different. With plethora of options such as Flutter, React Native, Ionic etc., you can pick the best framework that perfectly suits your project requirements. However, here we would be making a comparison between two most popular platforms; Ionic and React Native. But before we begin with the main battle, let’s start with a short introduction about both React Native and Ionic. React Native React Native made its first appearance in the year 2015, developed, and extensively supported by Facebook. It is a JavaScript framework used for creating native mobile and web applications using JavaScript. It thoroughly supports both Android and iOS platforms and uses designs similar to React, offering an interactive mobile user interface. However, remember that React Native does not offer any support to a hybrid or HTML5 app. Ionic Ionic is one of the popular open-source platforms employed for building outstanding hybrid mobile applications. It was initially introduced in 2013 by Drifty Co. As such, the apps built with JavaScript, CSS, and HTML5 basically opt for the Ionic. The framework uses Apache Cordova and Angular, which makes a preferred choice for the developers. Like React Native, it also supports the cross-platform app development. The tools like SaaS and CSS etc. further aid in the development process. The Major Difference – Native and Hybrid It is evident from the short introduction of the React Native that it only used for developing the native mobile and web applications using JavaScript. The developers can share the codes across the dais by rendering the native components. The User Experience works in close proximity with the other native apps following the models offered by the Operating System. The React Native also offers improved performance as well as seamless animations. However, you would only get the desired result if the bridge components are written for the native components and offers a default. On the other hand, Ionic is a staunch supporter of the hybrid application development framework. It usually makes use of the web-based technologies for writing and rendering the application and chooses Cordova or PhoneGap for the assessment of native features. It also comes with a feature Ionic Native. But don’t think that you can create native apps using this feature. It is also known as the ngCordova, which proves helpful in utilizing the existing Cordova and PhoneGap plugins. The Difference in Technology Stack If we talk about the React Native, it is based on the principle ‘Learn once, write anywhere’. This means that the developers will have to follow the set of rules and make use of the native components. React Native emphasises keenly on the UI with the presence of the UI components. For instance, you know that Android has a highly customizable toolbar, which is absent in iOS. So, you can use something else. A number of components have equivalents and if isn’t there you can simply segregate the platform-specific logic. The theme of the Ionic is ‘Write once, run anywhere.’ It offers a comprehensive Software Development Kit to help create hybrid apps. As told, it gets the fuel from web technology and is built on the top of Angular. You can create multi-platform apps using minimal codebase. The well-experienced Angular developers will find no problem whatsoever when working on with the Ionic framework. It also offers built-in components, which simplify the process of app development and enhances the speed as well. What about the Performance If we have to tell you who the better performer is amid the two competitors, then certainly, React Native is the winner. The reason is that it is known for its closer resemblance with native and comparatively faster. However, the developers need to make some changes in the platform-specific component. React is also known for its stability and ideally suitable for developing large-scale apps. On the flipside, building native apps are costly than the hybrid apps. Ionic is slower than React Native due to the presence of the WebView. It mainly uses the mobile-optimized HTML, CSS, and JavaScript components. When you want to add that hybrid factor in your native apps, you can choose Ionic. In addition, it is also good at developing faster prototypes. The bottlenecks in the performance also occur due to the presence of a number of callbacks in the native codes. The Ease or Difficulty of the Language The Ionic framework is closely related to the Angular, which is another very popular JS framework. It follows the Mode-View-Controller model clearly and has got the logic completely separated. It utilizes the HTML view for its views. React Native also is based on JS framework and its code is similar to HTML, known as JSX. The JSX is quite an easy codebase to work with. However, if you are not working in a team or if there is a lack of collaboration, then you might find it difficult as it wouldn’t be as easy as editing the template files and writing CSS. There’s a difference between JSX and HTML as the former does not offer the theories of CSS entirely. Community and Plugins You would be delighted to note that while working with React Native, you would come across several plugins accessible on the NPM. In fact, the plugins are also available while using the PhoneGap or Cordova allowing you to straight away receive lot of plugins from other communities as well. Again, if you compare the

The Advantages of Hiring a Full Stack Developer to Develop MVP

Leave a Comment / Uncategorized /

But the question is, why not hire a full stack developer who can carry out the project with comprehensive responsibility and put all his experience behind to deliver the best. Moreover, it would also prove out to be budget-friendly as well.It wouldn’t be wrong to quote that the Minimum Viable Product or the MVP is the spinal cord or backbone of your mobile application. As before constructing a building, it is necessary to lay the foundation stone and prepare a base structure; which supports the entire edifice, similarly the MVP offers a robust foundation to your mobile application. It allows you to implement the most important features of your application and the essential feedback from your potential customers to know if you can mould your idea to give it a proper shape. Most of the start-ups begin with the MVP development before moving on to the full-fledged web product. Well, this is the right step as it minimizes the risk of product failure upon its launch. Of course, you would be looking at professional developers to cater the job, unless and until you are extremely confident that you can build the MVP on your own. But the question is, why not hire a full stack developer who can carry out the project with comprehensive responsibility and put all his experience behind to deliver the best. Moreover, it would also prove out to be budget-friendly as well. Defining the Full Stack Development When we talk about the full stack development, it combines both the major roles required to develop an app; the front-end and the backend besides creating the database and connecting it completely. You can choose one or more full stack developers to do the wok depending on the project requirements. As the name indicates, full stack developers cater the entire project from designing the concepts to deploying the product appropriately. You can categorize the entire full stack development in three stages namely: The Front-end or the Presentation Layer This focuses on the client-side development of the app where you create the User Interface. As a full stack developer, you need to be adept with front-end development as your role would be building a highly responsive and functional app. As far as the language is concerned, you should have a thorough knowledge of JavaScript, CSS, Bootstrap, and HTML. The bootstrap will help in designing the content and layout. Regarding the JavaScript frameworks, it is better to be familiar with React, Angular, and Vue.js. The Backend or the Business Logic This is known as the server-side layer of the application. You need to make use of the backend languages to develop the logic for the web app. Here too, you should have the expertise in two or more server-side languages or frameworks such as Node.js with Express.js, Ruby with Ruby on Rails or Python with Django and Java with Spring MVC etc. Java isn’t a dynamic language. If you are choosing the static language, you have to write more codes but it would be easier to maintain. The Database The database is also one of the crucial aspects of the backend programming. In this step, you need to precisely develop and maintain the databases and therefore, this is where your knowledge of database languages would play a key role. You can divide the database languages into two categories; Relational and Non-relational. The former is based on tables and rows for the data storage while the second stores the data in the JSON format. Now, coming to the important database languages, which you should know include MySQL, PostgreSQL, and MongoDB. The first two languages belong to the Relational category whereas the MongoDB is used as the non-relational database. The Full Stack Developers or the T-Shaped Professionals A full stack developer is always considered as Jack of All Trades but Master of few. They have adequate familiarity with most of the technologies and programming languages used for developing the mobile apps. And in the mobile development industry, these expert all-rounders are also termed as the T-shaped professionals. Is it not sounding odd? The question is who are these professionals and why are they called so. Well, the answer is that he is a highly skilled person who not only adequately experienced or is the master of one or more niches but also has well-versed knowledge of other niches as well. They are largely different from the I-shaped professionals whose expertise lay in one or two areas only. The full stack developer possesses knowhow about wide range of software and programming languages apart from the front-end and the backend development. So, they have an upper hand over the conventional developers and that is why their demand is more in the market. Plus, they keep on updating their skills and technical knowledge as new technologies and software keep coming at regular intervals. They are well acquainted with the modern and recent trends prevailing in the mobile app development industry. If as a client you are going with the traditional method of app development, then you need to hire the project manager, the front-end and the back-end app developers separately, the UI and the UX designers, the app tester etc. all individually. On the contrary, just by roping in for a full stack developer, you are banking upon a person who would carry out all responsibilities. This proves to be a great cost-saver, just imagine. Skills Required for Full Stack Developer We have already discussed in the earlier paragraph that in order to become a full stack developer, you should have extensive knowledge in three important domains including the front-end development, the backend development, and familiarity with database and web storage. In addition, we have also mentioned about the important programming languages and frameworks that you need to learn and use optimally for building the app. This included popular JavaScript frameworks like Angular, React, and Vue.js for the front-end development, languages such as Ruby, Python, Node.js, PHP and Java for the server-side building lastly the

Newspaper App Development: Must Have Features & Cost Estimation

Leave a Comment / Uncategorized /

Do you still have the fond memories of those days when people would eagerly wait for the daily newspaper every morning? In fact, many of you would agree that lots of people were so addicted to it they would begin their day with a newspaper in one hand and a cup of tea in another. First things first, they wanted to read the important headlines to get familiar with what’s happening in the domestic and international circuit. The electronic media arrived later after 2000 and since there was, flood news channels, running 24×7. However, as times have progressed, literally those days have gone. And most of you are aware of the prime reason; the advent of News and Newspaper App has caused a major setback for the print media industry. Newspaper App Market Insights Now, let’s take this into the deeper insights and put some numbers and stats to explain how even the big bosses like ‘The New York Times’, ‘The Wall Street Journal’, ‘The Guardian’, ‘The Times of India’ have seen the slump in their readership. According to the Pew Research Center, there has been a fall both in the circulation and revenue of the newspapers in the United States, which is stated to decline by 10% in the weekday. Similarly, if we talk about India, the readership has decreased as per the May 2017 report of Audit Bureau of Circulation (ABC). Even the story of European countries such as Britain, France, and Germany is no different. Statista indicates that the turnover of the retail sale of the periodicals in the U.K. has gone down significantly in the last decade. As such, it was about 3971 million in 2008, which declined to 2718 in 2016. Let’s now analyze how news-based apps and social media forums have played a key role in converting the readership of global audiences. According to one of the available data, around 67% of the Americans gather news from social media. Likewise, if we perceive the percentage of news app usage in various countries, then Sweden tops the list with 37%, followed by South Korea and Spain with 33% and 27% respectively. The Category of News-Based Apps Before we go into the details of features and discuss the monetization policy of the newspaper app, it’s essential to first look into the two types of news apps. News Aggregator Apps The first category is News Aggregator, where the mobile applications cover incidents occurring in the regional, national or international arena. In fact, this type of news apps is widely popular amongst the users as it makes them aware of the world’s happenings with just a few taps around. But at the same time, the choice of news content to be displayed on the app is also extremely important. It should necessarily be interesting and something that grabs the user’s attention instantly. You need to decide whether your app would be paid or accessed free of cost. Besides the vital news such as political, sports, crime, business, entertainment, and weather report, you can also inform the users about the important events and exhibitions around the various cities. You can include optimistic news that provokes positive thoughts and inspires other people to do the same. Mobile Apps for News Resources The second category belongs to mobile apps for news resources. This would prove beneficial for people who are the owners of newspapers and web media. You can develop a news app version of your daily such as what ‘The Times of India’ has done to enhance the number of readership across the globe. The readers get breaking news immediately and read about the incident in real-time. It also allows users to choose their niche of interest. Some individuals have a keen interest in going through the political beat while some are curious to know what’s happening in the share market and business world. And with the 2019 General Elections just a few months away, the news-based apps are going to surge up as far as numbers of downloads are concerned. App Monetization Strategies The news-based app falls within the on-demand app category. Therefore, it’s important to decide the monetization of the Newspaper Mobile App. Of course, you as the owner want to earn more bucks at the end of the day and choosing the right monetization strategy will lead to the path of success and profit bearing. Here, you have got a few options to look at such as the advertisements and the paid subscriptions. The Advertisements It is rather easier to find good paid advertisements for the daily. You know how newspapers nowadays are full of ads. But when it comes to the news app, the scenario undergoes a change. They have a different advertisement format such as splash ad during the release of the app and not so noticeable ads that continuously gets displayed on the screen. Paid Subscriptions This is rather a common app monetizing strategy. But the question is why a user would pay an amount to subscribe to get the news. So, you can offer two separate versions; paid and free. You can offer personalized services for the paid version and keep it ad-free. Organizing Events Well, you can opt for this third option if you get a good positive response from the potential audiences. You can organize some events such as social debates on current issues and advertize your news apps on such platforms. Must-Have Features in the Magazine/Newspaper App So far we have been shedding light on the different types of news apps and discussed the various app monetization strategy. Now, let’s focus on the most essential features of the newspaper app that is summed below: Log-in or Registration Like most of the on-demand apps, the news app also requires users to first register their account. It can be done through email-id or mobile number. The users can also use social media platforms to log-in fresh into the app. Creating the User Profile After the person has signed in into his
