Swift Or Reactnative: Which Framework To Choose For Your Ios App Development?
Hefty sales volume of iPhonesacross the world is making iOS app development much popular and growing industry. Today there are many iOS app development frameworks available in the market. But let us have a look at the two most popular iOS native app development platforms: ReactNative and Swift.
What is React Native?
What is Swift?
Swift is the framework which is general purpose and compiled programming language developed by Apple. Developers can create iOS, macOS, watchOS, tvOS, Linux and z/OS apps using Swift. Swift is designed to work with Apple’s Cocoa and Cocoa Touch frameworks and the large body of existing Objective-C code written for Apple products.
How do they compare
Now let us compare both frameworks on the basis of 3 key parameters to help you make the right decision about your native mobile app development project.
1. Development process
- The process of SwiftNative app development and ReactNative app development is almost similar. The only difference is in the order of consecutive tasks. An advantage of ReactNative is less development time. With developing a simple app using React Native, a developer can save about 30% development cost and time as compared to Swift framework.
- ReactNative offers hot reloading in terms of design layout which keeps the app running and also allows adding new file versions which have been edited at run time. This helps in preserving the states and this feature proves to be helpful when you are working on app user interface (UI).
- However, ReactNative does not have all the componentsas available in Swift framework. It is an open source platform and gaining fast popularity because of active support and community of Facebook. There are number of functions which are unavailable in React Native so at times, developers need to build the modules on their own.
- Also Learning Swift was relatively easy, as it is similar to many languages like Java, C++. Furthermore, Apple’s IDE (Xcode) is without any doubt very advanced and user friendly. You can use Storyboard and set up the app screens the way you want. This is something completely lacking in React Native.
- A Native mobile app development company considers performance as the important factor for any mobile app project. It is important to check which framework is provide better performance.
- There are three main performance factors to check. They are CPU usage, memory allocation and the energy impact on tasks such as first run, taking call, opening URL, etc. It is also important to check the speed of scrolling and opening language list to call i.e. check frames per second.
- It can be said that in terms of performance, both ReactNative and Swift have similar efficiency and behavior.
Tests have been performed for measuring the performance of both ReactNative and Swift frameworks.
- ReactNative wins over Swift as it is 1.86% more efficient than Swift. While performing the task, a spike was recorded in CPU usage and it was observed at the same time when login button was clicked.
- ReactNative again wins the addition and deletion tab being 1.53% roe efficient than Swift. While performing the additional and deletion of items from list, spikes were measured in CPU usage.
- In terms of page view, Swift beats ReactNative with 8.82%. Shifting from one page to another needs less CPU usage in Swift as compared to ReactNative.
- While using maps tab for find the current location, the CPU measurements were recorded and compared and it concluded that Swift is better than ReactNative.
- The offshore mobile app development companies in India have started considering ReactNativeas a first choice for developing any small-mid scale mobile apps because of the shorter development cycle and the cost efficiency. You can forgo the cost of two teams for android and iOS if you use ReactNative and it also has a reduction in resources employed.
- However, Swift is still the primary choice when it comes to developing Enterprise level mobile applications as there are no budget constraints in such cases.
Two applications, one in ReactNative and one in Swift, with same functionalities and UI were developed. While doing a performance review, it was found that Swift app was a much better performer than ReactNative app in terms of CPU usage, while in terms of GPU usage, ReactNative out performed.
Making a decision between ReactNative and Swift framework depends on your app requirement and complexity. For complex mobile application development, it is recommended to go with Swift based development. For simpler apps, ReactNative is a better option as it gives you quick turnaround and ROI. The major advantage of ReactNative is that it allows mixing of Swift with pure Java Script components. Which is why people consider ReactNatives the platform for future iOS app development.
