React Native vs Swift 2024 : Which is Better for iOS App?

Mobile applications are becoming more popular with powerful features, making them useful in many ways. While Android has a bigger market share, iOS has many applications in the App Store compared to Google Play. This raises the question of why developers prefer to develop more applications for iPhones than Android. Ideally, the norm is that most iPhone users have higher incomes, and they rely heavily on applications to achieve different tasks and objectives. That is why in this guide, we do an in-depth analysis of React native vs Swift since they both play a key role in iOS app development.

There are different scenarios where React native will be effective and not swift. Similarly, there are instances where Swift will be effective and react native not. For instance, when your iOS app should be compatible with all Apple devices and various features, Swift is the best option. React native, on the other hand, will be effective if your iOS app uses a simple code logic and UI design.

What’s more, Swift is effective when your budget isn’t limited, while react native is effective when the deployment is faster and reduced costs of development.

One element about Swift and react native is that they both have capabilities of executing promptly on iOS devices. The only difference that comes in is that developers should consider varied iOS programming languages and approaches required to develop a specific app.

Understanding Swift

This is one of the modern programming languages. It is an open-source language for programming developed by Apple for all iOS apps. Generally, Swift is known to be a general-purpose language for varied models in iOS app development.

Ideally, Swift is created for all iOS app development for all Apple devices. Swift plays a key role in having the developer’s attention for all iOS development services. Again, Swift was created with more advanced features to replace one of the Apple programming languages, Objective-C.

Among the giant applications created with Swift include Test Center, Lyft, SlideShare, Twitter, and Airbnb.

What are the disadvantages of Swift?

Before you consider hiring a custom mobile app developer for your iOS project, below are the pitfalls of Swift you should know:

Only for Apple Devices – Since Swift is a native platform, developers can only use it for native devices. Therefore, if you want to create both iOS and Android applications, this isn’t the right option for you because you will have to create separate apps, which will take more time and require extra costs.

Limited Talent – Even though Swift is growing rapidly, only a small pool of developers has knowledge of using Swift as the programming language for iOS applications. Therefore, it is hard to hire a swift developer.

Understanding React Native

As a beginner developer, you might get confused between React and React native. That is why it is crucial to differentiate between the two to ensure you select the appropriate option that will help you meet your project development objectives. Once you understand the basics of the two different languages, you will know that choosing to react native for your iOS app is the best solution.

React native is a JavaScript framework created with the intention of speeding up the mobile app development process.

We all know that JavaScript is among the top choice programming languages for many developers across the globe. As a developer using React native, you can share up to 70% of the code across different platforms. This, in turn, helps save the development costs and the overall time taken to finish the app.

Besides, react native enables developers to write code for both iOS and Android platforms.

Examples of giant applications developed with react native include Instagram, SoundCloud, Bloomberg, Walmart, and Facebook.

What are the advantages of React Native?

As a way of distinguishing react native from Swift, let’s take a deeper look at the advantages and disadvantages of both. Here are the advantages of react native:

  • Rich Library Support – When comparing the libraries and packages for react native and Swift, react native is way far with approximately 33,000 libraries and packages, whereas Swift has approximately 3800 packages.
  • Hot Reloading – this feature enables developers to visualize the codes, something that makes the whole app development process seamless and easy.
  • Highly Reliable and Safe – Since all native apps meet all the rules and guidelines for operating systems, they are highly reliable with high safety measures.
  • Improved Performance – Apps created with react native are made for a specific operating system, hence taking full control of the processing speed of the device. Apps of this kind are generally easy to use, and they perform better.
  • Easy to integrate – Using react native best practices for app development, you can easily integrate with other devices for easier navigation and performance. What’s more, you can integrate technologies such as AR, IoT, AI, and VR for a seamless experience when you use react native in your app development process.
  • Less Debugging – as a developer with expertise in react native design patterns, you will have an easy time monitoring bugs.

What are the disadvantages of React Native?

While React Native has incredible features, making it stand out, it has some major pitfalls that you should know. However, this shouldn’t be a big concern because the native team is always on the move, trying to find practical solutions to all these drawbacks. The React Native pitfalls include the following:

Fewer Wrappers – For developers to integrate native components, modules, and APIs into an app development process, they must write customized wrappers, something that consumes more time.

Complex Design – Both Android and iOS platforms have specific rules for publishing applications. As a result, developers often have a hard time creating high-end customized UI for React Native applications.

Extended testing period – Well, the React native apps are single-code source apps, something that makes the development process faster and smoother when compared to Swift. However, the same React native applications require more testing time, something that requires developers to put in more effort and resources.

Comparing React Native vs Swift: Which One is Better?

React Native vs Swift Which is Better

This section will give you a detailed comparison analysis between Swift and react native depending on some elements.

One key difference between Swift and react native is that Swift is ideal for native iOS app development, while react native is ideal for cross-platform app development.

The parameters below will show you a detailed comparison between Swift and react native. In the end, you will select an option that will work best for you based on the nature of your project.
