React Native vs Swift in 2024: Which is Better for Developing iOS Applications?

The best technologies for iOS app development are React Native and Swift. Swift is Apple’s proprietary software that helps developers build sleek apps that leverage native iOS features seamlessly. React Native is the preferred framework for developers looking to create cross-platform apps quickly and effectively, with JavaScript as the foundation language.

 

Then, which language is the best for app development? To find out, we will compare React Native with Swift. So that you can decide which is best for you.

 

What is React Native?

React Native is a JavaScript framework created to speed 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 on development costs and the overall time taken to finish the app.

React-native allows developers to write code for both the iOS and Android platforms. Instagram, SoundCloud, Bloomberg, Walmart, and Facebook are all examples of large-scale applications built with React Native technology.

Pros & Cons of React Native

 

S.N.

                      Pros

                  Cons 

1.  

Highly Reliable and Safe – Since all native apps meet all the rules and guidelines for operating systems, they are highly reliable and have high safety measures.

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.

2. 

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.

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.

3. 

Less Debugging: As a developer with expertise in React Native design patterns, you will have an easy time monitoring bugs.

Longer testing period: Since React native apps are single-code source apps, the development process is quicker and more efficient than it is for Swift apps.

 

What is swift?

This is a modern programming language. Apple created this open-source programming language for use in all iOS applications. Swift is generally regarded as a general-purpose language for a variety of iOS app development models.

Ideally, Swift is created for all iOS app development on 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.

Pros & cons of swift 

S.N., 

                  Pros 

                    Cons 
  1.  

Easy to Scale – Developers can effortlessly integrate new functionalities in swift applications

Only for Apple Devices – Since Swift is a native platform, developers can only use it for native devices.
  1.  

User Experience – It is easy & quick to install Swift apps. 

Limited Talent – Despite Swift’s rapid growth, only a small number of developers are familiar with using Swift as the programming language for iOS apps. As a result, it is difficult to hire a quick developer.
  1.  

Improved safety & performance – Ideally, Swift was created to enhance performance and safety measures, something Objective C didn’t have.

Higher cost for app development
