Creating a mobile app can give your business a competitive edge and help you engage with your customers like never before.
React Native Vs Swift: Choosing the Right One for Mobile App Development
However, choosing the ideal mobile app development framework is crucial for the project's success. Two of the most popular choices for mobile app developers remain React Native and Swift.
But which one should you go for? In this blog, we will explore the pros and cons of each to help you make an informed decision for mobile app development.
What is React Native used for?
React native is an open-source framework created by Meta (formerly Facebook) Platforms, Inc. It combines the best-in-class JavaScript libraries and React to build user interfaces.
React native allows developers to develop iOS, macOS, Android, Android TV, tvOS, Windows, and virtual reality applications. It uses JavaScript and JSX to create applications that render using mobile UI components, not webviews.
It also provides JavaScript interfaces for platform APIs, allowing access to features like the phone camera and user location.

Pros of React Native
Some of the pros of React Native are as follows:
-
Hot Reloading
-
Better Performance
-
Rich Library
-
Modules
-
Reusable Codebase
Hot Reloading
React Native allows developers to see changes made to the code on a preview window without refreshing the app. The modified code version is automatically reloaded while keeping the app state, allowing for quick modifications and adjustments. This feature speeds up the development process and provides immediate feedback.
Better Performance
It leverages native controls and modules of the operating system to create high-performing apps through Native APIs, enabling apps to run smoothly and as intended.
Rich Library
React Native boasts an extensive list of around 33,000 libraries and packages, which is significantly higher than Swift as it only displays 3,800 packages on its website. It is important to note that the number of packages does not necessarily reflect the quality of the language or framework.
However, it does indicate the dedication and eagerness of the community to contribute. This commitment plays a vital role in driving the development of any technology further.
Modules
In React Native, the modular architecture separates functions into flexible blocks, named modules. These modules provide enhanced coordination, versatility, and seamless updates in the app.
Reusable Codebase
React Native comes with a single code base that can be reused. This means that developers can write their code once and reuse it across multiple projects, which saves them a lot of time, effort, and cost.
Additionally, since the codebase is reusable, developers can easily maintain and update their code without having to rewrite it from scratch. This makes the development process more efficient and helps developers to deliver their projects faster.

Cons of React Native
Along with the pros, React Native also has a few cons as follows:
-
Upgrading Issues
-
Compatibility and Debugging
-
Lack of Custom Modules
Upgrading Issues
Each upgrade in the React Native platform brings improvement, however, one can’t always rely on automatic update implementation as they can face unpredicted issues when adjusting to the newer variation. Fortunately, there are some community guides and helpers that aid during the current and higher variation transition.
Compatibility and Debugging
React Native hasn’t reached its 1.0 version yet and it’s still in beta. This as a result causes developers to face package compatibility and debugging issues. There’s also a risk of some packages being left unmaintained and becoming incompatible with your project due to a large number of community packages.
Lack of Custom Modules
React Native still has some missing components and others may not be fully developed yet. This means you may need to create your own solution or modify an existing one.
This could lead to having three different codebases: one for React Native, and one each for Android and iOS. Due to this, the behavior and appearance of an app could be different on different platforms. However, these situations are rare and the chances of encountering such problems are quite low.

What is Swift used for?
Swift is a programming language developed by Apple for building applications for iOS, watchOS, and macOS. It combines various programming paradigms and supports Objective-C concepts like dynamic dispatch and extensible programming.
Swift addresses common programming challenges like null pointer dereferencing by providing syntactic sugar. It is a powerful and intuitive language gaining popularity among developers for its modern features and robust support for Apple platforms.
Pros of Swift
Using Swift for app development has the following advantages:
-
Fast Development
-
ABI Stability
-
Compatibility with Objective C
-
Safety and Performance Enhancement
Fast Development
Being an expressive and clean language, Swift is easier and more concise to read and write. It requires less code to perform the same task as Objective-C.
Also, developers don’t have to spend time and effort to track and manage app memory usage manually, instead, it is done by Automatic Reference Counting (ARC), leading to faster app development time.
ABI Stability
Application Binary Interface (ABI) in Swift is equivalent to Application Programming Interface (API). The ABI stability in Swift enables binary compatibility for apps and libraries, allowing code compilation using different versions of Swift and Objective-C to communicate.

Compatibility with Objective C
One of the advantages of using Swift as a programming language is its compatibility with Objective C. Both languages can be used in the same project, which can be particularly useful when developing large-scale projects that require frequent updates.
With Swift's modern syntax and features, developers can easily add new functionalities to their projects and integrate them seamlessly with the existing Objective-C codebase.
This ensures that the project remains maintainable, scalable, and future-proof, while also allowing developers to leverage the strengths of both languages to achieve their development goals.
Safety and Performance Enhancement
Swift focuses on its performance and speed as it was designed to outperform its predecessor. Also, its strong typed system along with its error handling capabilities prevents errors and crashes in the production environment.
Overall, it can be said that Swift comes with a shorter feedback loop that allows developers to identify and resolve errors instantly, minimizing the risk of low-quality code deployment.
Cons of Swift
Just like React Native, Swift also has some limitations, these are:
-
Small Community
-
Relatively New Language
-
Poor Third-Party Tools and IDE Compatibility
Small Community
Although it is just a minor disadvantage, the community of Swift is still relatively smaller in comparison to other languages. Although there is a growing community of Swift developers, finding ones with significant practical experience in the language can be challenging.
Relatively New Language
Swift might be one of the tough contenders in the programming world, but it’s still relatively new and has multiple issues that need to be addressed. Also, numerous tools and resources of the earlier Swift variations have now become useless with the newer ones.
