React Native Vs Swift: Which Framework To Choose For The Project?

Swift vs React Native

React-Native has been on the app development tech-radar for all the valid reasons for a little time now. It’s a framework that uses React to design the user interfaces for native devices. Facebook, Instagram and a large community of developers and corporations are responsible for maintaining it.

Learning Swift is relatively easy because it is similar to many languages (Java, C ++). But learning Cocoa Touch (iOS framework) is very much a difficult task.

The IDE (Xcode) of the Apple is used developing the application which is undoubtedly highly advanced and user-friendly. On the other hand, React Native enables developers to create applications for iOS, Android, and UWP (universal Windows platform) with the help of JavaScript. It’s a cross-platform mobile framework/infrastructure, but with a difference.

With the help of React,  you are not creating a ‘Mobile Web App’ (this is a Web App wrapped in a native container). It compiles your JS codebase to a mobile app, which is similar to the iOS app built with Objective-C or Android One using Java. Therefore, React-Native is having an advantage of both native and hybrid technology.

React Native Vs Swift

But how does it in actuality compare against Swift? Since both small and large projects can benefit from React Native, a comparison between React Native (RN) and Swift can reveal the real benefits.

React Native Vs Swift?

Development Process

  • The development procedure for both RN and IOS is almost similar. The major difference is simply the sequence of consecutive tasks. One prime advantage of React Native over Native iOS is the time of development. For example, for a simple app, the technical team at Netguru found that 30 percent of mobile development costs and time efficiency.

When you talk of design layout, React Native provides hot reloading that helps app in running mode and allows adding new versions of a file that have been edited at the runtime. It helps to protect all your states, especially when you are working on UI.

  • Clearly, React Native may not have all components similar to the Swift. It’s an open-source project, which is rapidly gaining popularity due to an active community and Facebook support. Although many functions are still unavailable, some scenarios can use React’s Native Modules tool with the NPM package which works for some issues. But sometimes the developers will have to create the necessary modules themselves.

For example, making shadows work properly, similar to what they do on iOS, there’s no custom solution in the React Native. Thus, you will have to adjust and customize to achieve the desired results.

  • Performance is an important consideration for mobile apps, particularly to see which framework is more efficient. CPU usage, allocated memory and energy impact are the three main factors that help in deciding the performance parameter for various tasks like taking a call, the first run, opening a URL. It is also important to keep in mind the speed of opening and scrolling of language list to call (frames per second).
  • The React Native is good as, if not better than  Native iOS for CPU usage and energy impact. Applications developed with RN is likely to allocate more memory than those written in Swift. Also, it’s true that the RN apps reserve approximately 20 MB of memory for RCTbridge and its various components. Therefore, in terms of performance, both have the same behavior and efficiency.


A number of startups have started considering React Native due to the small development cycle and clear cost efficiency. It is easy to learn and simplify or troubleshoot React Native, making training part easy for companies. With React Native, you go before the cost of two separate teams for iOS and Android, there’s a decrement in the whole resources employment.


The answer to React native vs Swift lies in the complexity of the app. For more complicated applications, it’s better to write in Swift or else your app simply does not measure up against the competition. For simpler apps, React-Native provides budget and timeline benefits that are difficult to ignore. Both React-Native and XAMARIN have proven themselves to be more ‘native’ than other cross-platform or wrapped web applications in the market.

React Native

The huge advantage with React Native exists in enabling the mix of Swift / Objective-C controllers with pure Javascript components. The reason for high production is faster development of Javascript’s CSS layout model than Swift or Objective C.

Therefore, if the strength of your team is JS and you are on a strict timeline and budget, then for an application which is not very complicated,  React Native may be the answer to your query
