React Native vs Swift Comparison for iOS Apps

Mobile apps have become an important part of our lives. They help us be more efficient and organized when it comes to business and our personal lives. So, it’s only natural that you’ll want to use the best tech when it comes to building an iOS app. When it comes to iOS app development, emerging technologies are important. That is why we’ve conducted a React Native vs Swift comparison test!!

Although both are excellent at what they do, there are differences that you should know about. Each offers different benefits for developing iOS apps. Make sure you choose one that best meets your personal needs.

What is Swift?

Swift created for Apple for Linux and iOS-powered devices. It is a new, multi-paradigm, general-purpose programming language. You can also use it to design apps that are compatible with all Apple products, Cocoa, and Cocoa Touch frameworks.

What is React Native?

Facebook created React Native as an easy-to-use framework that lets people develop mobile apps. It uses JavaScript codebase to design apps on Android and iOS platforms. Many other Native applications need to change the programming language when changing the platform. React Native uses one code across multiple platforms. This makes it easy to use and very popular among new developers.

What to take into consideration for a React Native vs Swift Comparison

When doing a React Native vs Swift comparison test, we made sure to include relevant topics. Factors that would be important and helpful to readers who are into iOS app development. These are the results we received when comparing React Native to Swift:


When developing an app with Swift, you will be coding from scratch. This means more work and polishing. But, you’ll find that the app easily integrates with the platform. This is due to the iOS-native designed language. When developing an app with React Native, you’ll be using JavaScript. This is good for saving time. But prohibits you from taking advantage of all the functions Swift has access to. This means that some tweaking will need to take place when switching platforms.


Performance is another big factor to take into consideration during a React Native vs Swift comparison. Several tests show that an app built by React Native performs differently than an app built by Swift. Even if they are doing the same task. React Native tends to be better for CPU usage, while Swift does better with saving memory.

Development Time

When you compare Swift to React Native based on development time, you should keep a few things in mind. JavaScript gives Native an advantage when you want to build a mobile application that is simple. Swift takes longer, but integrates seamlessly across iOS platforms.


When doing a React Native vs Swift comparison, money is a big factor for many companies. Startups need to consider the time it takes to learn the language and develop an iOS app. React Native is easier to learn and use, but does not offer the same level of complexity as Swift. You have to decide what’s more important for your company’s needs here.


When building mobile apps, React Native acts as a middle man between the platform and code. It depends on internal libraries and APIs to make the application work. In a React Native vs Swift comparison, you’ll find that Native is less stable and under-performs due to this. Swift also comes on top when it comes to heavy computational tasks and graphic effects.

Advantages of Swift

As a new technology, Apple has made developing new mobile apps a little bit easier. The curve for learning the language is steep. But your ability to build mobile apps that are more complex will give you an edge over the competition. A React Native vs Swift comparison has shown Swift to have an advantage in other areas as well. This includes the use of memory and creating intricate codes that leverage all that iOS has to offer.

Advantage of React Native

JavaScript powers React Native, which has its benefits. It allows users to learn one code that can be utilized on different platforms. When doing a React Native vs Swift comparison, Native beats Swift in some areas. It can help you save time and money with its easy-to-use language. This makes it great for start-ups and developing simple mobile apps.


Although there is no clear winner here, they both have their advantages. By doing a React Native vs Swift comparison, you can make an informed decision that will meet your needs.
