Swift vs React Native: Which Is Best For Mobile Apps

If you want to create an iOS app, you have a variety of languages to choose from. The most popular languages for designing iOS mobile apps are Swift and React Native. The language you choose for the mobile app will influence not just app cost estimates and development time but also the app’s potential to scale in the future.

The first thing to ask yourself before choosing between these two languages for iOS development is whether you want to build a cross-platform app or an iOS-native app. Of course, there are additional aspects to consider before making this decision. In this blog, we’ll compare Swift vs React Native and contrast these two technologies on a variety of criteria, ranging from performance to simplicity of use.

But before that, let’s have a look at the basic overviews of both these technologies.


Overview Of React Native

Facebook originally launched the React Native project in 2015. It is an open-source UI software framework. React Native development, or simply “RN”, is a popular JavaScript-based mobile app framework that lets you create native-looking iOS and Android apps. Using this technology, you may construct applications for a variety of platforms with the same codebase. It allows developers to leverage the React framework alongside native platform features to create apps for iOS, Android, Android TV, macOS, tvOS, Windows, Web, and UWP.

It has become one of the most popular mobile development options in just a few years. Some of the world’s most popular mobile apps, such as Facebook, Instagram, Skype, etc use React Native development.

Pros Of React Native Programming

Faster development

React Native is a JavaScript-based technology. You can easily find a great percentage of the code for your project on the Internet. So, if you start building your iOS app with React Native technology, it will take much less time than Swift. 


React Native technology requires less effort for bug tracing and debugging. 

Less Budgeting 

With React Native, you can create amazing iOS applications at a very low budget. You can start building your project with a smaller team, which eventually reduces costs.

Hot Reloading

Developers can use this feature to visualize their code. The hot reloading feature makes the whole development process easier and more productive.


You can easily scale your mobile applications’ functionality with custom or existing JavaScript modules. 

Cons Of React Native Programming 

Apple App Store Restrictions 

The Apple App Store will reject your React Native application if it uses libraries that dynamically update native code. 

Complex Design

IOS and Android both have different design guidelines. That means developing a high-quality custom UI with React Native is difficult for programmers.

Slow Testing Process

React Native allows developers to build mobile apps faster, but it takes a lot more time than Swift to test a React Native app. React Native applications need extra precision and time for running tests.

Regular Updates 

Updates are very frequent in React Native technology. That means if you develop your app with React Native, you have to release your app updates regularly.

Overview Of Swift

Apple Inc. created and released Swift in 2014. It is a general-purpose, compiled, and multi-paradigm, programming language. The Swift programming language is mainly designed for iOS, iPadOS, macOS, tvOS, and watchOS. It is both powerful and easy.

Swift is basically an extension of Apple’s Objective-C programming language, which has been in use since co-founder Steve Jobs licenced it as part of the formation of NeXT decades ago. Swift is designed to be a simpler and highly expandable version of Objective-C. For many years, it was simply assumed that Swift was not suitable for Windows users. This, however, proved to be a misconception. 

Swift officially published toolchain images for Windows 10 in September 2020, with the package having practically everything a developer may need to create and run Swift programs on Windows.

Pros Of Swift Programming 


Swift is an open-source programming language that is distributed under the Apache License. 


Swift provides strong typing and a better error handling system. That means it is good at preventing errors and code crashes in production. 

Easy Scaling 

Swift is easily scalable. It can be extended with new features as needed. So, it is future-proof as it allows you to scale your app seamlessly when needed.

Less Line Of Code

Swift is very easy and concise. It needs less code to perform a task that will need more code when performed using React Native.

Fast Coding 

As Swift needs less code to perform any task and is also easy to understand and code, developers, can build applications faster with Swift.

Cons Of Swift Programming

Only Build Apps For Apple Devices.

Apple developed Swift for only its native platform. Therefore, it is only used to build Apple platform applications.

Swift vs React Native: Detailed Differences

Now, let’s see Swift vs React Native to decide which is best for IOS development.


If you want to build your mobile app with the minimum possible cost, then JavaScript will definitely win the battle of Swift vs React Native on the basis of cost-efficiency. According to PayScale, the average salary of a React Native developer is $97K in the United States. 

React Native Salary

At the same time, the average salary of a Swift developer is more than $108K in the United States.

Therefore, if you want to hire someone or work with a team of developers to build your IOS mobile application, you have to pay more to developers when choosing Swift.


According to Stack Overflow’s Developer Survey, Javascript is number 1 in the list of most widely adopted programming languages whereas Swift is not even present in the top 10 list.

Development Time

React Native is a javascript based technology and javascript is one of the most widely used languages. If you try to build a mobile app with React Native, you can easily find a large number of resources on the Internet. So, you don’t need to build your app from scratch. On the other hand, Swift developers have very few resources. So, they most have to start their app from scratch in most cases. So, React Native is the clear winner of the battle of swift vs React Native development time.

UI Comparison

The UI components in React Native are designed to look like those in native apps. Because React Native manages native components, app components must be updated whenever the platform’s OS is updated. However, when there is a fatal issue, this feature can cause the app’s UI to crash. Material design components must be accessed through third-party libraries if developers want to employ a consistent UI across all devices and OS versions. 

Apple Inc., on the other hand, created Swift for native development on its own platform. As a result, it naturally employs UX principles and smoothly combines iOS UI designs. However, development for the Switch must begin from the ground up, with each UI component being developed separately.

submit Assignment


Because using React Native to build graphical effects is cumbersome, the framework integrates native programmes into projects. This method enables the developer to produce a variety of assets and tools to help in the development process. When compared to apps built with frameworks, Swift apps perform better in general. Despite the fact that Swift Apps need a lot of processor power, they run better than React Native apps.

The Learning Curve

As told earlier, React Native is a JavaScript-based technology. So, any JavaScript programmer can easily learn and start their mobile app development with React Native.

On the other hand, Swift was created by and for Apple. Swift guarantees power and easiness of learning. So, this round of Swift vs React Native learning curve is a tie.


React Native is powered by JavaScript, which is one of the most popular coding languages; however, React Native does not produce truly native apps. It uses internal APIs and libraries to make the app function. Therefore, placing a middleman between the code and the platform is necessary.

On the other hand, Swift creates native applications that can fully take advantage of the platform’s capabilities. Swift performs better when dealing with graphic effects and computationally intensive jobs. So, Swift can be a better option for juicing out the platform.

Documentation and Community Support

React Native is an open-source platform that allows contributions from developers across the globe. Swift developers can get technical advice from the public platform and forums. 

React Native offers accurate, clear, concise, and informative documentation. Swift is also a convenient programming language with regularly updated documentation.

Platform Maturity

React Native and Swift both are fairly new technologies. Swift was introduced in 2014, whereas React Native was introduced in 2015. Both are in the development process, and there are no notable differences between them. Swift was created to replace Objective-C. 

Developing a new programming language to replace the old one is a complex process as many software may be using that old technology. 

On the other hand, React Native is a new technology that JavaScript, a well-known technology, supports. Therefore, examining the code, identifying issues with the framework, and finding errors are simpler.
