Swift vs. React Native: Key Differences You Must Know

Swift vs. React Native

If you own a phone, which it is? There are just two possibilities for us: Android or iPhone. Both of them are leading the market share according to buyers’ preferences. It is stated that iPhone buyers tend to have higher incomes and spends on in-app purchase! Furthermore, the iOS platform employs applications that are more user-friendly and dynamic. Swift and React Native are the most widely used applications of them all. So, let’s closely analyze these applications to know better.

What is Swift?

Swift is a high-level, influential, general-purpose language. Apple Inc. and the open-source community-developed Swift. The application was created to help developers create apps for iOS devices. In contrast to other application development languages, it is simple, concise, and versatile. Let’s have a look at the pros and cons of Swift language.

Top Benefits of Using Swift

Here are some of the benefits that are making Swift a popular choice over its predecessor Objective-C.


Swift is speedier than its predecessor Objective-C, as the name implies. The LLVM tool of Swift compiles the whole code to machine code quickly. Swift application development leverages the process of development.


Swift is an easy-to-read language because of the one-liner code. The syntax of Swift is simple and easy to grasp. Thus, it is easier for beginners to understand and develop applications.

User Experience

It takes less time to install and less memory usage on your device. Swift application development is lighter, which provides a friendly user experience. Hence, application development companies hire iPhone application developers who can build applications in Swift.


If you want to scale up the project in no time, then Swift is there to help! Swift uses the XCode IDE to improve code, resulting in high-performance apps.

Obstacles of Swift

Besides all its praise, there are some of its disadvantages to acknowledge.

Less Popular

Swift has a limited community to deal with while being a robust and in-demand language. Only a few Swift developers can develop applications on iOS platforms. Thus, it can be a challenge for new talent who want assistance.

Newly Developed

Swift is only 7 years old, despite being an easy-to-understand language. Developing application through Swift is easy. Even though Objective-C is an older programming language, it is more preferred to Swift.

Famous Swift Applications

  • WhatsApp
  • LinkedIn
  • Slack

After going through Swift’s features, we’ll move to React Native, Swift’s counterpart.

What is React Native?

React Native, on the other hand, is a JavaScript framework and open-source UI software. Meta platforms created it for both Android and iOS platforms. React Native was developed to solve cross-platform development issues.

Key Advantages of Using React Native

Although, it is an easy framework to use, here are some of the pros to develop cross platform application.

Time Efficiency

React Native code is deployed to both platforms in no time. Plus, the developers can view changes in application code in the preview window. This makes real-time feedback will be beneficial during development projects.

Quick Update

React Native has simplified the process of updating applications. The updating process is called OTA (Over the air) updates. For React Native developers, this update is easier and faster.

Premium Automation

It is not only about writing code, testing, fixing, etc. The software development process is lengthy to complete. React Native avoids your interaction related to dull tasks and uses third-party services. These services used by React Native are Britrise, Appcenter, Amplify, etc.

Modular Approach

React Native follows a modular architecture approach. This approach helps to divide the program functions into smaller and flexible modules. It also benefits in versatility, coordination, and seamless updates. Furthermore, these modules, like Web APIs, are reusable code blocks.

Obstacles of React Native

On the contrary, there are some limitations to this excellent framework, and they are enlisted below.

Lengthy Testing

Despite a single line of code, source code is used to speed up the development of an application. But on the contrary, testing takes a longer time than expected. Therefore, running tests on both platforms makes testing lengthy.

Case Insensitive Language

React Native is built on JavaScript, a liberally typed programming language. This feature doesn’t impose restrictions on variables. That means nobody can verify which variable contains what value. And this feature poses a great security threat.

Popular React Native-based Applications

  • Facebook
  • Walmart
  • Bloomberg

Now, after looking at all the benefits and limitations of both the applications. You must have got a clear vision of what handles what. However, for a more comprehensive understanding, we’ll go over some fundamental differences between the two.

Swift vs. React Native

  • React Native provides an almost native-like experience, but Swift itself is a native application.
  • Swift is more stable than React Native.
  • Due to working on cross platforms, the development cost is higher for React Native than Swift.
  • The availability of engineers for Swift is fewer in number than for React Native.
  • React Native works well for cross platforms, but for efficiency, Swift overrules!
  • React Native uses JavaScript, which is the easiest language to learn. In contrast, Swift has a steeper learning curve.
  • Swift being a native application, provides high performance than React Native.


Swift and React Native are both excellent for creating mobile applications. However, it is not possible to select one of them because they are both unique and platform preferred for their respective purposes. Your project needs and application requirements define which application to use. You can take assistance from React Native application development services or Swift application development services. Moreover, you can also hire iPhone application development services if you wish to work on iOS platforms.

Frequently Asked Questions


1. Which platform is better React Native or Swift?

Depending upon the project’s requirements, applications in use, project duration, and the platform in use. You have the option of using React Native or Swift. However, the distinctions listed above can help you distinguish between the two. You can also hire application development companies to assist you.

2. When to use Swift?

If your project involves the development of iOS platforms or any other Swift application. Then Swift provides more stability, new features, and high performance to your applications. You can also take the help of the Swift application development services or hire iPhone development services.
