React Native Or Swift: Best Framework for Mobile App Development?


Share on LinkedIn

Why should we distinguish between Swift and Reactive Native? Is there anything same in that or differs in one? Understand the features that differentiate both app development frameworks here!

What this article is about: With this article, we are going to discuss some of the significant differences between Swift and React Native for CI / CD tools based on critical factors such as performance and coding speed, application size, debug and test experience at the time of mobile app development.


Both the development of Reactive Native (RN) as well as compiling JavaScript (JS) code similar to Objective-C and an iOS app in a mobile app built with Android using Java. There is a double benefit. This can enable the development of both large and small projects. A clear comparison between React Native (RN) and Swift can reveal real benefits.

Let’s Start with React Native:

1. React Native comes with Random Access of module building, native parallel leaching, inline requirements, RAM bundles, and inbuilt in some more networks.
2. This ramework often comes with some hurdles that have to be contested while coding, such as enabling push notifications in applications, frequent crashes in JavaScript Core (VM) React Native, memory issues used by iOS and Android, and overhead bundling is used.
3. The time required to create a response app is less than the time needed to develop a Swift app.
4. React Native allows the development of native mobile applications for iOS as well as the Android platform, with the help of a single JavaScript codebase. It uses the React.js library to create an accurate native mobile application.
5. React Native helps compile a JavaScript codebase for mobile apps using Java code, similar to an iOS app built with Objective C or Android One using Java.

Let’s discuss SWIFT:

1. Swift is a native iOS programming language or framework which allows the development of the mobile app from the core. This is contradictory to React Native, where the same code applies to platforms – Android or iOS.
2. Swift installs and leverages all iOS UX principles.
3. Coding and CPU performance are slightly lower on the speed scale than React Native.
4. Swift includes the use of automatic reference calculation (ARC) correction, which can help the developer avoid repeated memory leaks in the app.
5. It is easy to understand, interactive code, and easy to learn.
6. The Swift is designed to ensure safety.


Apple supports Swift, and Facebook supports React Native. It is built one step ahead of Objective C, after supporting all OOPS programming concepts and most iPhone applications.

React Native is not making any native applications but getting used for writing the code to works across the platforms. It works wonders by taking advantage of internal APIs and libraries to make the application work. It is about connecting a middle-man between the code and the platform.

On the other hand, Swift creates a native app that can take advantage of all the possibilities of the platform. This framework performs better with graphic effects and computationally-heavy tasks. Although Swift can create highly performing applications, it is not helpful with code optimization.

Reactive Native is supported by JavaScript that makes coding and debugging easier. It helps compile JavaScript codebases for Java code, such as mobile applications built with Java (Android) or Objective C / Swift (for iOS). These enhance reactive native application development and prevent all comparisons between reactive versus Swift.
