Mobile apps are expected to generate more than $613 billion in revenue by 2025 (source: Statista). There are about 1.5 times as many apps on the App Store than there are on Google Play, and Android has a 70% market share compared to iOS’s 30%.

Wait a minute! This blog post does not aim to argue between Google Play and the App Store.

We would like to draw attention to the fact that developing a robust mobile application for your business is the best way to expand it quickly.

React Native vs Swift – the two most popular technologies that enable the smooth and effective creation of mobile apps. Today, through this blog, we will understand when to use which technology and which is the best fit for the project at hand.

Can React Native surpass Swift?

Well, as per our 20+ years of experience in web and mobile app development, sometimes this is the case. As an illustration, you must quickly develop an iOS app version that functions like the Android version. Furthermore, you can easily expand the program’s functionality thanks to React Native’s modular design. But when it comes to making sophisticated apps, Swift is the better programming language.

Choose React Native when prioritizing cross-platform development efficiency. Ideal for projects with a shared codebase, it allows simultaneous deployment on iOS and Android, reducing development time and costs.	Swift offers optimal performance and takes advantage of native iOS features, resulting in a polished and native feel. Choose Swift when creating a seamless, platform-specific experience for iOS.

he functionality and performance of an iOS app are largely dependent on the technology selection. Therefore, you must be aware of their quirks to select the best one for your current project.

So, what are you waiting for? Let’s dive deeper into both of these technologies and find the winner!

Introduction of React Native

React Native is a popular JavaScript framework created by Meta and was first released in 2015 to accelerate mobile development processes. It enables developers to use a single codebase to simultaneously create native-like experiences on both the iOS and Android platforms using the JavaScript library React.

Most novice programmers get confused about React and React Native. You should be aware of the fundamental distinctions between React vs React Native before learning the language.

React Native combines the efficiency of web development with the performance and appearance of native apps, enabling faster development cycles and code reuse. It’s famous for its hot-reloading feature, facilitating real-time code changes, and its extensive community support.

The amazing features of React Native collectively make it a popular choice (liked by 29% of worldwide developers) for mobile app development, especially when there’s a need for efficient cross-platform development without compromising on native performance.

Let’s cover all such features.

Google Trends result shows that in the last one-year, Swift has remained more search technology than React Native. It indicates that top web and mobile app development firms are now getting interested in Swift. However, React Native remains the most popular framework when quick and efficient development is required.

Result: Being a JavaScript framework, React Native is more popular in the market than Swift

2. Application Architecture

React Native uses a JavaScript-based approach with a single codebase for both iOS and Android, employing a virtual DOM for efficient UI updates. Dedicated React Native developers leverage native components and APIs, allowing seamless integration with platform-specific features. A bridge connects the JavaScript thread and the Native thread in React Native. The JavaScript code uses this functionality to interface with the platform and the Native API.

Swift, on the other hand, out of React Native vs Swift follows an imperative paradigm and uses Apple’s Cocoa Touch framework. Swift applications generally have a native feel due to close integration with iOS APIs.

Swift applications use a variety of architectures, including MVVM, MV, Clean, and Viper. Components are generated in a clean architecture using Xcode templates. These template elements are modifiable to accommodate future requirements.

Viper is used with SwiftUI to divide functions, facilitating app development and making them easier to test and manage.

Result: React Native generally offers a simpler architecture with a single codebase for iOS and Android. Swift, while robust and native to iOS, involves platform-specific development, potentially making it more complex for cross-platform projects.

3. Programming Language

While comparing React Native vs Swift, Swift is a multipurpose compiled programming language, while React Native uses JavaScript. JavaScript is the most preferred option for making dynamic websites and web apps.

Explore the power of JavaScript programming language.

Apple created Swift, a statically-typed programming language intended to develop iOS, macOS, watchOS, and tvOS apps. Swift is renowned for its performance, modern syntax, and safety features. Swift offers a targeted and optimized experience for Apple’s ecosystem, with features like optional and automatic memory management adding to its dependability and efficiency. React Native’s JavaScript, on the other hand, offers flexibility and broad applicability.

Result: Developer preferences and project requirements frequently influence the decision.

4. Learning Curve

JavaScript, which has been around for a long time, is attached to React Native, making learning reasonably simple. However, dedicated developers using React Native may feel stuck in place because the development of mobile and web apps differs. However, to reduce learning curves and alleviate this situation, React Native has offered sizable libraries and comprehensive documentation.

Swift has a steeper learning curve, especially for those new to iOS development or without experience. Moreover, Swift’s syntax and iOS-specific concepts may require more time to grasp.

Result: Out of React Native vs Swift, React Native is relatively easier to learn

5. Developer’s Availability

JavaScript is the reason behind React Native’s fame. Approximately 65.36% of developers say that JavaScript is their favorite programming language, according to Statista. This data demonstrates the popularity of React Native over Swift.

Finding JavaScript developers is quite simple because the language is so well-liked by the developer community. Furthermore, Swift is still relatively new. Consequently, it is more difficult to come across a group of qualified Swift developers or Swift development firms.

Result: React Native is a clear winner out of React Native vs Swift in terms of popularity and developer’s availability.

6. Performance

Many variables affect how well Swift vs React Native performs, such as GPU speed, CPU usage, memory usage, etc. Swift performs better than React Native in terms of CPU consumption but React Native performs better in terms of memory usage and GPU speed.

Find the best practices to optimize the performance of your application.

In scenarios where maximum performance is critical, such as high-end games or resource-intensive applications, Swift might be a preferred choice for iOS development. However, React Native’s performance is often sufficient for many applications, offering the advantage of code sharing and faster development across multiple platforms.

Result: While choosing React Native vs Swift, you should consider specific project requirements and performance expectations.

7. User Interface

When creating a visually appealing UI for a native app, out of React Native vs Swift, Swift is more user-friendly than React Native and allows seamless integration with the iOS platform. Apple launched a new Swift framework called SwiftUI at WWDC 19, and it enables declarative user interface development. Therefore, Swift developers can create a completely native and enhanced user experience by using SwiftUI from the ground up.
