Did you know that over the last few years, Android has managed to take up the market share by almost 73% – whereas iOS apps make up for a “measly” 26%

However, the variety of applications on iOS is more than what Android has right now. And that’s where React Native Vs Swift comes in, as a secret ingredient that gives more of a free haven to developers to use their creative ink!

That being said, if you’re contemplating which app to go for at the end of the infamous React Native vs Swift tussle, this post is for you.

We’ll talk about the essential steps to building an iOS app (*that part comes at the very end), the overall importance of React Native vs Swift, and some of the React Native vs Swift performance stats. 

Let’s get started.

React Native Vs Swift – What Do You Need To Know?

React Native Vs Swift

React Native vs Swift are two popular programming languages used in the development of mobile applications

While React Native is a cross-platform framework that uses JavaScript, Swift is a native programming language developed by Apple specifically for iOS and macOS app development

What Is React Native?

As stated earlier, React Native is an open-source framework developed by Facebook that allows developers to create mobile applications for iOS, Android, and other platforms using JavaScript and React, a popular JavaScript library for building user interfaces. 

The good thing about React Native is that it follows the “write once, run anywhere” (WORA) principle, which means that developers can write code once and use it across different platforms, reducing the need for separate codebases for iOS and Android apps. 

What is Swift?

Up next, we’ve got Swift.

This is a programming language developed by Apple for iOS, macOS, watchOS, and tvOS app development. It was introduced in 2014 as a successor to Objective-C, with a focus on safety, performance, and modern syntax. 

Swift is a statically-typed language, which means that the type of a variable must be explicitly defined during declaration. 

If you’re looking to build apps with Swift, it has a powerful feature called “optionals”, which allows developers to handle nil or null values safely.

What Pain Points Does React Native Address?


While React Native offers cross-platform development, it relies on a bridge to communicate between the JavaScript code and native components, which can result in performance issues, especially for complex applications with a lot of animations or heavy computations.

Native UI Components: 

Although React Native provides a set of pre-built UI components, it may not have all the UI components that are available in native development. 

This can sometimes require additional effort to customize or create custom UI components.

Third-party Libraries: 

While React Native has a large community and ecosystem of third-party libraries, not all native libraries are available in React Native. 

Developers may need to write native modules or use third-party libraries specifically designed for React Native, which may not always offer the same level of functionality or support as their native counterparts.

What Are The Benefits of React Native:

Cross-platform Development: 

React Native allows developers to write code once and use it across different platforms, which can save time and effort in developing apps for multiple platforms, such as iOS, Android, and others.

JavaScript and React Expertise: 

If you are already familiar with JavaScript and React, transitioning to React Native can be relatively easy, as the syntax and concepts are similar, making it accessible to web developers who want to build mobile apps.

Rapid Development: 

React Native offers a hot-reloading feature, which allows developers to see the changes in real time without rebuilding the entire app, making the development process faster and more efficient.

Large Community and Ecosystem: 

React Native has a large community of developers, which means there are abundant resources, documentation, and third-party libraries available to support the development process.

What Pain Points Does Swift For iOS Address?

Platform Limitations: 

Swift is a native programming language developed by Apple, which means it can only be used for iOS, macOS, watchOS, and tvOS app development. This limits the ability to develop cross-platform apps for other platforms.

Steeper Learning Curve: 

Swift has a steeper learning curve compared to React Native, especially for developers who are not familiar with iOS app development or have no prior experience with Objective-C, which was the predecessor to Swift.

Longer Development Time: 

As Swift is a statically-typed language, it requires more time and effort to write code with explicit type annotations, which can slow down the development process compared to dynamically-typed languages.

What Are The Benefits of Swift

Native Performance: 

Swift is a native programming language developed by Apple specifically for iOS app development. 

As such, it provides direct access to iOS APIs, allowing for optimal performance and efficiency. 

If anyone is looking to build apps with Swift, they should know that Swift’s performance is comparable to Objective-C, the traditional iOS app development language, as it is compiled into machine code, resulting in fast and smooth-running apps.

Robust and Safe: 

Swift has been designed with a strong emphasis on safety and robustness. 

It enforces strict type checking and provides features like “optionals”, which help prevent common programming errors such as null pointer dereferences and unexpected crashes. 

This makes Swift code more reliable and less prone to bugs, resulting in more stable and secure iOS apps.

Modern Syntax and Features: 

Swift has a modern and expressive syntax that is easy to read and write. It includes features such as type inference, closures, generics, and pattern matching, which make it more concise and powerful compared to Objective-C. 

Swift also supports the latest language advancements and updates, providing developers with cutting-edge tools and capabilities for iOS app development.

Interoperability with Objective-C: 

Swift is designed to work seamlessly with Objective-C, allowing developers to use existing Objective-C code in Swift projects and vice versa. 

This means that developers can leverage their existing iOS libraries and frameworks written in Objective-C, making it easier to transition from Objective-C to Swift or use Swift in existing iOS projects.

Strong Community and Support: 

Swift has a rapidly growing community of developers, which means there are abundant resources, tutorials, documentation, and support available. 

Apple actively maintains and updates Swift, providing regular releases with new features, performance improvements, and bug fixes. This ensures that Swift remains a vibrant and supported language for iOS app development.

Faster Development Time: 

Swift’s modern syntax, type inference, and powerful features enable developers to write code more efficiently, resulting in faster development times compared to other languages. 

Swift’s interactive development environment (IDE) in Xcode, Apple’s official IDE for iOS app development, also provides advanced tools and features that help streamline the development process, making it more efficient and productive.

Future-proof Language: 

Swift is designed to be the long-term replacement for Objective-C and is actively maintained and updated by Apple. It is expected to have a long lifespan and will likely continue to be the primary language for iOS app development in the future. 

By choosing Swift for iOS app development, developers can ensure that their apps are built using a modern, supported, and future-proof language.

In summary, Swift offers numerous benefits for iOS app development, including native performance, robustness, modern syntax, and features, interoperability with Objective-C, a strong community and support, faster development time, and future-proofing. 

So to answer your question about React Native Vs Swift, while one language is better, our vote kind of leans towards Swift.

But then again, it’s a matter of technical requirements. 

To some developers, React seems like a better programming environment because of the nature of the project. 

Anyhow, moving on, let’s take a cursory look at React Native vs Swift Performance based comparison.

React Native Vs Swift – Which One Gains Precedence As The Best Mobile App Development Platform?

React Native Vs Swift platform

When considering which platform to use for mobile app development, there is a great debate between React Native and Swift. 

Both of them offer unique advantages and limitations that must be taken into account before making a decision. Ultimately, the choice will depend on the type of application you want to build, budget constraints, and the skill set of your development team.

When selecting one or the other platform comes down mostly based upon personal preference but also taking into consideration what type of application needs are going to be built, budget, and experience level within the development team. 

For example, if creating many versions across different platforms then go with React Native since most code can be used again without too much trouble whereas if working on just mainly IOS then go with Swift since all frameworks are built specifically towards Apple products.

What are the essential steps to building an iOS app?

  1. Planning: 

The first step in building an iOS app is planning. You should determine the purpose of your app, who will use it, and what features it must have to make it successful. You should also consider the potential costs associated with developing and maintaining an app, such as design, programming, and distribution costs.

  1. Design: 

After planning your project, the next step is designing your app’s user experience (UX) and user interface (UI). UX includes the logic behind how users interact with your product while UI focuses on visuals like buttons, fonts, colors, etc. 

For instance, you may focus on creating a minimalistic design that relies heavily on intuitive interactions for users when setting up their accounts. 

  1. Develop: 

Having planned out how users are intended to interact with your application, you’re ready to develop its back-end components that enable desired features to be implemented into a working prototype or Minimum Viable Product (MVP)

  1. Test: 

Once any necessary code has been developed and integrated within your mobile application product, testing should begin before its release to eliminate errors that could otherwise negatively impact user experience and customer satisfaction levels.

This can involve manually testing specific scenarios through both physical devices along with virtualized emulator environments enabled by respective operating system vendors such as Apple’s Simulator app supported from within Xcode itself. 

  1. Release & Maintenance: 

With all facets related to development fully finalized, releasing an application onto either iTunes Store or Google Play would facilitate end-user downloads upon availability across all respective platforms.
