React Native vs Swift in 2024: Which One is Better to Develop iOS App?

In 2024, the debate between choosing React Native and Swift is more about iOS app development. Choosing the right technology can make a huge difference in performance, the speed of development, and the overall user experience. Whether you’re a developer selecting the right technology for the next project or a business owner planning an application, understanding each of their strengths and weaknesses is important.

Let’s discuss a detailed comparison of React Native and Swift to help you make the best decision in developing iOS apps in 2024.

What is React Native?

React Native is a famous framework developed by Meta(Facebook), which enables JavaScript and React developers to build mobile apps. With this framework, the advantage lies in cross-platform development. In other words, a single codebase will cover both iOS and Android, hence saving one a lot of time and resources.

What is Swift?

Swift is Apple’s native programming language for developing iOS, macOS, watchOS, and tvOS apps. Swift was introduced in 2014. It is a high-performance language, safe, and expressive, and boasts a native performance that’s hard to beat. It is the go-to choice of developers when it comes to building high-quality iOS apps with a seamless user experience.

Difference between React Native and Swift

1. Speed and Efficiency: React Native vs. Swift

Usually, speed and efficiency are critical factors in choosing an app development platform between React Native and Swift. High-performance Native apps can be built with Swift, which generally performs much better—they are compiled directly into machine code. This offers faster execution and smoother usage in resource-intensive applications such as games or apps with complicated animations.

React Native is quite efficient for most standard applications but doesn’t match Swift’s performance. Because of its use of a JavaScript bridge to pass information to the native components.

That inherently causes slight delays and may not be quite as effective for heavy computational tasks as Swift. But over the last couple of years, React Native has improved dramatically. They released the Fabric architecture and Hermes engine which helped narrow the performance gap.

Swift leads when performance-critical applications are in view. Otherwise, React Native is second to none when absolute speed is not the ultimate concern of the app.

2. Development Speed and Ease of Use: React Native vs. Swift

Where React Native scores big is in how fast and easy it is to create an app. The biggest advantage that React Native has over other frameworks, besides being the largest and most widely adopted by developers. It is the ability to reuse code across platforms, reducing development time significantly.

One codebase for React Native supports creating apps on both iOS and Android. For startups and companies looking at launching apps on several platforms in a short time, React Native is ideal for such a wish.

React Native also boasts an active open-source community, comprehensive libraries, and third-party plugins that can hasten development. Moreover, features such as hot reloading, where the changes become visible instantly without needing to recompile the whole application, further streamline the development process.

Swift has a bit of extra overhead, but it provides rapid development with robust tools like Xcode, Swift Playgrounds, and a huge array of native APIs. Swift syntax is clean and fairly easy to learn if you’ve had experience with C-based languages.

Swift, however, doesn’t have as much cross-platform help as React Native does, and it usually involves longer development time if the development should be done on both iOS and Android.

This leaves React Native as the winner if the speed of development and cross-platform are the most important things. For iOS-focused applications only, Swift has a much more streamlined development experience, with native performance being a bonus.

3. User Experience: React Native vs. Swift

Think of the user experience, which is a concern for any application. Here is where the native has an advantage out of the box with Swift. Applications developed with Swift can utilize all iOS standard components and APIs and, therefore, seamlessly integrate into the iOS system. The result will be an application that feels and looks just like a real iOS application: smooth animations, responsive interfaces, and such.

React Native does a very good job of emulating native components, but there can be subtle differences between the UI and UX, especially if it is an app with intricate animations or custom-designed UI. React Native has libraries to help you get close to native, but you may have to do more work to get the finesse like that from an app fully implemented using Swift.

Swift is the way to go for an ideal iOS user experience. You should go for React Native if you are willing to make some compromises in place of quicker and cross-platform development.

4. Cost Efficiency: React Native vs. Swift

In many cases, this is a question of the budget, and React Native can be more friendly because of its cross-platform nature. It allows having one code for both iOS and Android, which reduces the cost of development and maintenance considerably. That is why React Native will ideally fit startups and small businesses that have to be very sensitive about the budget.

Swift is usually more expensive because it offers awesome performance and a high-end feeling of an application. More specifically, there is necessary development of two standalone codebases for iOS and Android, which consumes more time, requires more developers, and therefore costs more money.

However, in such cases, when a strategy is to run iOS-only, the long-term advantages of Swift justify the initial investment made for performance and native feature development.

React Native is an undisputed winner in cost-effectiveness, especially for multi-platform projects. Swift can be cost-effective, but mainly for iOS-only projects when the investment will be justified by the app’s goals.

5. Community and Ecosystem: React Native vs. Swift

React Native boasts of an enormous, active community, meaning third-party libraries, plugins, and tools abound that can hasten development. The community-driven ecosystem means developers will find a wide variety of resources, tutorials, and forums to find solutions and stay up-to-date with the latest trends.

Swift has fewer community members, though backed by strong support from Apple. On the other hand, it enjoys Apple’s strong and well-documented tools and resources. The Swift ecosystem is growing steadily due to lots of contributions from the developer community and continuous improvements at Apple’s end.

React Native has a much bigger and more vibrant community; finding support or resources for it is fairly easy. The Swift ecosystem is smaller but steadily growing and extremely reliable.

6. Security: React Native vs. Swift

For most apps, security becomes the utmost priority, and on that note, Swift by default carries loads of native security. Due to Apple’s strict guidelines and Swift itself, with features like Automatic Memory Management, Type Safety, and Error Handling, provide an entirely secure environment for app development.

Since they make use of JavaScript, React Native apps are usually secure but somewhat vulnerable to certain types of attacks if not kept in check. Extra measures of security and practices must be taken into consideration to make React Native apps secure.

Swift would, for sure, be the preferred choice when it comes to security. React Native could still be secure, but it requires more diligence with some extra measures of security.

Future Prospects of React Native and Swift

Both React Native and Swift are evolving: They are actively maintained, and new features are added to them all the time. React Native keeps pushing to fill in the gap with native performance through innovations such as the new architecture Fabric and Hermes engine.

Swift, on the other hand, has the advantage of being Apple’s anointed language, so it can’t help but be state-of-the-art for iOS development. And it is going to keep being a safe, future-proof choice for iOS developers with Apple continuing to improve the language and its integration with the iOS ecosystem.

Both technologies are going to do great. React Native is getting a lot more performant and versatile, while Swift keeps holding its spot as the gold standard when it comes to native iOS development.
