**2.What is cross-platform app development? why choose it? **

Currently, the software market is full of cross-platform apps. It raises the question why so many companies are choosing cross-platform apps. So, before delving into this article, let’s clarify the necessary concepts.

Each platform (Android and iOS) has a specific language that developers use to write apps. Java for Android and Swift and Objective-C for iOS. Each platform has a specific set of APIs and SDKs that are also used for native development. Applications, programming interfaces, and development toolkits developed in these languages are generally all native.

 The corollary of native app development is to get an application that can only run on a specific operating system. It causes difficulties in maintaining and updating applications. Additionally, if a company wants to create native Android and iOS apps, it has to do the work twice. That means you have to develop apps separately for both overall systems. This process will lead to a significant increase in development costs.

Next, let’s look at a cross-platform solution. You can see many cross-platform frameworks that have modules for accessing operating system functionality through a native middle layer. Cross-platform apps are basically halfway between web and native solutions. All web applications are geared towards creating platform independent software, but there are two drawbacks:

  * Only accessible when the device is connected to the Internet.

*Responsive web apps cannot offer the same functionality and convenience of mobile apps.

Cross-platform apps are the next generation of apps because they are platform independent and provide concurrent access to device functionality. Plus, it can run effectively offline and be uploaded to app marketplaces just like native apps. The situation can be achieved with the best cross-platform frameworks such as Flutter and React Native.

Now that we know the differences between the cross-platform and native approaches, we’ll discuss their pros and cons.

Cross-Platform Pros

Objectively, native apps run smoothly and are more intuitive than cross-platform apps because the structure of native apps is created in the platform. While these are significant advantages, there are also many drawbacks. Developing them takes more time and money than a cross-platform solution, especially if a company needs apps that run on iOS and Android. Developers have to build two independent apps. This doubles the cost of development, support, maintenance, and adding new features. Also, it takes a lot of work for developers to learn specialized languages like Swift, Objective-C, Java, etc.

Cross-platform apps are slower and less interoperable with operating systems than native apps, but using the Flutter framework eliminates these problems almost entirely. Developing React Native apps can also help overcome these obstacles and bring cross-platform apps to top positions in the market. On the plus side, cross-platform solutions are cheaper, faster, and easier to develop. Since all platforms require a single common app, delivering updates is also less complicated. We can see what cross-platform app development can do in itself, but we also need to choose the best framework for 2020. That’s why the question “Which language is better between Flutter and React Native?” becomes very relevant to current trends.
