If you’re looking to build iOS app, you’ve got a list of languages to work with. Swift and react native are some of them. A question we often get in 2021 is whether to choose React native or swift for iOS app development. Both platforms are used to create excellent native apps that run smoothly on iOS, but they need different skill sets and resources to build. There are many factors to consider while choosing a language for app development. So here we will compare Swift vs React Native with different parameters to help you decide the most appropriate one for your project. But before digging to the comparison, let us see overview of each technology in detail.

What Is Swift?

Swift is a modern, general-purpose and multi-paradigm programming language designed by Apple to build applications for iOS, Mac, Apple Watch, Apple TV, and Linux OS. It is distributed on Apache License, that makes it available for community to use. Swift is easy to read, write and maintain with human friendly syntax. Also, it interoperates with objective C and Apple’s Cocoa and Cocoa touch frameworks. Modern software design approach makes it an efficient, expressive and reliable general-purpose language to develop complex apps with fast performance.

Slideshare, Airbnb, Twitter are popular apps built with Swift.

What Is React Native?

React Native is a cross platform open source native app-development framework for iOS and Android that is maintained by Facebook. Main focus is on Android and iOS. There is no official support for macOS and watchOS, react native works on these platforms also. React Native is written with combination of XML-Esque markup and Javascript that is also known as JSX. It is supported by Facebook.

Facebook, walmart, instagram, Wix are some of the popular apps build with React native.

Swift Vs React Native-

1. Architecture-
Swift-
Viper, Clean, MVVM, MV are some architectures used for apps built in Swift. Clean architecture has Xcode templates that generate components and these template components can be modified according to the requirements. Viper architecture is used with SwiftUI that separates functions, which are easy to test, maintain and helps in rapid app development.

React Native-
React Native possesses a bridge between Native thread and Javascript thread. According to this functionality, Javascript code communicates with the platform and Native API. In IOS, React native uses JavascriptCore separately to run code, and it combines JavascriptCore within the android app. This may increase the app size and resulting in performance issues.
