React Native Vs. Swift – Which to Choose for an iOS App Development?

Developers are exciting as they have multiple programming languages, libraries, frameworks, and other tools for mobile app development. They can pick appropriate and suitable tools to make a perfect mobile app with the specific requirements of Android and iOS app development.

In some cases, developers are very confused when they have to choose one over other tools as there are multiple frameworks that contain similar functionality and features but make a competitive edge over each other.

Similarly, the war between React Native app development and Swift app development has been going on for so long. React Native vs. Swift debate starts whenever a developer starts developing a mobile app for cross-platform. Before differentiating React Native and Swift app development, let’s first understand where they are used and what cross-platform applications are?

Cross-Platform Application

Developing a mobile app that can run on multiple platforms, mainly iOS and Android, is called a Cross-Platform application. Developers can easily build apps with the same codebase for both platforms. There are many cross-platform app development companies that deliver result-driven services and consult you on why you have to choose Cross-platform applications.

However, you must contract with the terminology “Hybrid app development,” and if you think they are the same, you are wrong enough. Both are different and play different roles, so don’t think they are similar. You can differentiate it based on app performance, customization, UX, and navigation pattern.

Although cross-platform apps will provide simple installation, reliable functioning, and low production costs as well as you can expect robust UX and navigation patterns. Today’s cross-platform app development is common thanks to the React Native, Xamarin, and Flutter frameworks.Cross-platform app with React Native app development

What is Swift App Development?

Swift is a programming language specifically for iOS, iPadOS, macOS, tvOS, and watchOS. Swift app development offers contemporary programming features, and writing Swift code is enjoyable, which developers admire. The syntax is short and descriptive. Swift code is secure by default and results in blazing-fast software.

Swift is a multi-paradigm, all-purpose programming language, Apple and the open-source developer community created it at first. When this language was introduced in 2014, Objective-C, Apple’s previous programming language, was mostly intended to be replaced.

Since Objective-legacy C’s has been eliminated by the language, writing code is now incredibly simple and has almost no disadvantages. The simplest method for developing an iOS app is this.

The process of developing a Swift app so that it may operate on many platforms is known as cross-platform development. Swift is ideal for applications that require complex infrastructure, native iOS functionality, and in-app purchasing.

Pros & Cons of Swift App Development

With the additional ease and involvement of well-known scripting languages, Swift app development combines the effectiveness and performance of compiled languages. Let’s look at some of the advantages and disadvantages of this Programming Language.

Swift app development Benefits


Rapid development process

Swift is simpler to understand and write because it is a clear, expressive language with a streamlined syntax and grammar. Compared to Objective-C, it is far more succinct, which results in less code being needed to do the same task.

Simplify Apps’ Scalability

You receive a product that is long-term and can be expanded with additional features as demanded in addition to a shorter development time. Swift app development projects may usually be scaled more easily. For long-term investment, the fact that Swift app development is more likely to be supported by Apple than Objective-C should also be given considerable thought.

High Performance

The language was first created to emphasize performance and speed to exceed its forerunner. In particular, the original version boasted a 40% improvement in performance over Objective-C. Swift is literally swift when it comes to measuring the app’s performance.

Safety and Security

Swift’s safety is one of its greatest strengths. Error handling features and strong typing avoid code crashes. The amount of time and effort required for bug repair is decreased since developers can quickly identify and correct flaws in the code.

Integration with Objective-C

Comparison of React Native App Development vs. Swift App Development

Let’s compare in-depth to analyze the best framework or programming language for iOS app development.

Faster Development

If you are asking for only iOS app development, then swift can help you the best as it is mainly introduced for the iOS platform. On the other hand, React Native is also the second best option if you are seeing your app for the long term. Maybe you will have to build for Android, so ReactNative code is easy to reuse for Android app development. Both can give you the fastest development but React Native app development gives the opportunity to build further with the same codebase. 

Programming Languages

React Native is a framework that uses Javascript as a programming language. The fan following of JavaScript is huge, and that’s why there is huge community support for beginners or intermediate-level developers.

If we talk about Swift, it is itself a programming language that is built in the replacement of objective-C. Apple Company developed this language to build their products.

User Interface

Application components resemble native ones in appearance. React Native employs native components, so developers can be certain that their applications’ features will update immediately in response to any OS UI upgrade.

Swift does a terrific job integrating into iOS design and utilizing UX concepts as the primary iOS language created by Apple for designing apps. But creating an app using Swift is like starting from scratch when creating a native app. As a result, each component needs to be designed specifically for it and polished to perfection.

App Performance

Another thing to think about is the performance of Swift versus React Native. A Swift app will often perform better than a framework. Swift has a higher performance than React Native, despite the fact that executing an application on it might use more CPU resources.

Using the React Native framework while working with graphic effects might be challenging. ReactNative offers developers the option of using custom code within the application, as well as a variety of resources and tools to address various issues.
