React Native for iOS: Build apps faster and scale easier

React Native for iOS: benefits for business

Choosing a technology stack for an iOS application is not as easy as it may seem at first sight. Though native development languages have proven to be reliable, this option might not be the most profitable for some businesses. In trying to reduce the project cost, a lot of startups go for React Native for iOS instead. But is it as good as Swift or Objective C? If you’re considering building an iOS app for your business and wondering if React Native app development is the right choice for your vision, this article can give you some answers, as we’ll provide valuable insights about the technology, explain how it can be helpful to your project, and compare the framework with other tech choices.

What is React Native?

React Native (RN) is an open-source framework introduced by Facebook. RN combines the best of both web and native app development. It leverages the advantages of React — a highly popular JavaScript library for building user interfaces — and applies it to mobile app development, providing a seamless, smooth, and high-performance user experience comparable to apps built with native languages like Swift or Kotlin. React Native enables a single shared codebase, which results in reduced development time, cost savings, and easier maintenance. You can use the framework in your existing Android and iOS projects or create a new app from scratch.

Which technologies are used for iOS development?

React Native for iOS compared to other development options


Launched in 2014, Swift stands as a robust and approachable coding language, ingeniously designed by Apple for the explicit purpose of app development on iOS, macOS, watchOS, and tvOS platforms. Swift has gained immense popularity due to its modern syntax, high performance, and security features. No wonder, many businesses have adopted Swift for their native app development.

Objective C

Objective C is an object-oriented programming language that was the leading development language for iOS and macOS before Swift appeared. Although it has gradually been replaced by Swift, Objective C still maintains a strong presence in the iOS development community, especially for maintaining and updating older applications.

React Native

Using React Native for iOS development is possible, as it enables creators to construct applications across both mobile platforms. You can write a single code and adapt it to either operating system, and the app will have a native look and feel. The framework is more affordable than native technologies, and still it gives high-quality results.

Xamarin, Flutter

Other cross-platform frameworks can also deliver decent performance and cost savings, but each has its limitations and trade-offs. Xamarin uses C#, while Flutter uses Dart, both of which may have steeper learning curves or narrower community support for specific needs. Compare these options thoroughly and ensure they align with your team’s expertise and goals.

Benefits of using React Native for iOS

The primary objective of any startup is to launch the product to market as fast as possible, without compromising on quality or user experience. These are some of the benefits of React Native that help entrepreneurs achieve these goals:

Native experience

React Native lets you create native-like apps and doesn’t compromise users’ experience. It provides a set of native components that map directly to the platform’s native UI building blocks. Hence, users won’t be able to see any differences between a native app and one built with React Native.

Reusable codebase

React Native facilitates the development of a unified codebase and tailor-made component variants for each platform, ensuring smooth functionality on both iOS and Android devices. If you decide to expand and create an Android version of the app too, it will also require much less resources, since you won’t need to build it from scratch. You would only need one React Native team to maintain multiple platforms.

Speed of development

React Native’s shared codebase, hot reloading, and reusable components significantly decrease the time it takes to develop and deploy iOS apps. This means you can get your app to market faster and quickly iterate based on user feedback or new feature ideas.

Lower development costs

In general, React Native development costs 30% less than building apps using native languages. Developers charge for hours needed to create the product, and since React Native allows us to build apps faster, it also reduces the price.


According to Statista, JavaScript takes the first place among the most popular development languages hence, the task of finding developers that can use React Native for iOS development is much easier.

Strong community support

Given its widespread popularity and backing from tech giants like Facebook and Instagram, React Native boasts a vast and active community. This means that you can expect continuous updates, improvements, and access to a wealth of knowledge from peers who have faced similar challenges.

React Native vs Swift

In this article, we would like to compare React Native with Swift, as it’s the most popular native technology for iOS development. Objective C is used less frequently and mostly in combination with Swift. It’s difficult to choose between them, so let’s figure things out. For clarity, we have made a table with the differences:

Native look and feelHigh performanceBroad functionalityCost- effectivenessCross-platformFast updatesSuitable for enterprise apps

Swift is tailored for iOS, so it offers higher performance and better responsiveness. It also allows developers to create broad functionality. With Swift, the app will have access to native APIs and all the device’s features like contacts, camera, push notifications, etc. Swift also enables you to make iOS apps compatible with other Apple products like Mac, Apple TV, iPad, and Apple Watch.

Developing an enterprise app using React Native can be a bit tricky because it’s based on JavaScript, which doesn’t have specific data types. With the lack of type safety, the app can become difficult to scale. On top of that, you might face issues with refactoring the app. One way to fix these problems is by incorporating TypeScript into your project, but in that case, you would need additional time and effort.

On the contrary, Swift has concise syntax and it’s more suitable for enterprise-level apps. In other words, you’ll write less code with Swift, making it more manageable — a crucial factor for a large app. Plus, Swift comes with some handy features perfect for enterprise projects, such as efficient memory management, flexible data types, well-organized architecture, and a robust error-handling system.

React Native

Cost-effectiveness is one of the main benefits of using React Native for iOS compared to Swift. As you can see, the hourly rates of Swift developers can be quite high while React Native development companies can charge you less.

LocationSwiftReact Native
USA$100 - #350$90 - #300
Western Europe$80 - #250$70 - #200
Eastern Europe$50 - #150$40 - #120

The framework might not be the best option for enterprise apps, but it might definitely suit startup projects better. React Native provides enough scalability and will not let you down at the initial stages. And when your business starts to grow to enterprise scale, you can gradually switch to native technologies without spoiling the user experience.

Moreover, with React Native you can launch your startup for both iOS and Android platforms with fewer resources. It would take a lot more time and be much more expensive with native development, while time and money are the most important factors for any startup.

Apple doesn’t allow over-the-air (OTA) app updates. However, using React Native for iOS development offers you the flexibility to make crucial adjustments without submitting your app to the App Store every time. Teaming it up with CodePush, which is a tool that updates JavaScript code, can further streamline this process. This is not possible if your app is built with Swift. In that case, you’ll have to create a new version of the app and submit it to the App Store for approval.
