The mobile app industry has been growing a lot because of new technologies. Both Android and iOS are getting more popular thanks to these improvements. This has led to the creation of many tools and ways to make mobile apps in the last ten years.

Two of these ways are React Native and Swift. They have become really famous and lots of big companies and developers use them to make apps. People who know a lot about this stuff are talking about which one is better for making strong iOS apps.

This is a big topic because big tech companies all around the world are using both React Native and Swift to make apps for different devices. To help clear things up, let’s compare React Native and Swift in a detailed way.

What is React Native?

React Native is a popular tool that many developers use to create mobile apps. It was made by Facebook (now called Meta) back in 2014, and it’s really liked by developers because it helps them make apps that work on different types of phones.

One cool thing about React Native is that it lets developers reuse parts of their code, which saves time and effort. Also, many people know how to use it and can help each other out. Plus, it has some easy-to-use building blocks and tools that make it simpler to create apps.

React Native is used by some really big and well-known companies all around the world. These companies include:

  • Facebook
  • Walmart
  • Skype
  • Tesla
  • Wix

What is Swift?

It came out around the same time as React Native in 2014. Before Swift, Apple used another language called Objective-C. But Swift was brought in to replace it and it’s much more up-to-date. The good news is that Swift is free to use for people making iPhone apps. It’s like a tool they can use to build cool stuff.

Some well-known apps that were built with Swift include:

  • Slack
  • LinkedIn
  • WhatsApp
  • Uber
  • Airbnb
  • Truecaller
  • Medium

Pros and Cons of React Native


1. Reusable Codebase

React Native has a cool feature – you can write code once and then use it for different projects at the same time. This saves developers time, money, and effort because they don’t have to start from scratch each time.

2. Highspeed, Flawless Performance

Native apps are designed to work on a particular operating system, making the most of the device’s processing speed. These apps are known for their stability, flawless performance, and seamless operation.

3. Simple to use

React Native’s user interfaces are simple to use and understand, making it easy for people to learn how to use the app and move around in it.

4. Advanced Developers Tool & SDK

React Native developers have access to a variety of libraries and packaged solutions that connect with an up-to-date operating system. They use a JavaScript library to create excellent iOS and Android systems.

5. Cost-Effective development

Opting for a cross-platform framework results in budget-friendly development right from the start. With a single codebase, less time and effort are needed to build an app, leading to reduced development costs.


The main drawback of React Native emerges when it’s used to build large-scale applications. While it excels in crafting small apps and managing minor updates and shifts, its performance diminishes when handling heavy applications. The expenses, time investment, effort, and compatibility issues tend to increase substantially when dealing with more extensive projects.

Pros & Cons of Swift

Let’s take a closer look at the advantages and disadvantages of Swift to gain a better understanding and knowledge of this programming language.


The Apple team has ensured strong compatibility between Swift and Objective-C, allowing developers to use both languages within the same project.

This compatibility is particularly useful for working on large and complex projects that need to be updated or expanded. iOS app developers can enhance their projects by utilizing Swift alongside the existing Objective-C codebase.

Furthermore, Swift is versatile and suitable for both front-end and back-end applications. This flexibility enables developers to recycle and share code, which significantly reduces development efforts and speeds up the overall process.

Due to the growing demand for Apple products, Swift has gained immense popularity. It’s now a widely adopted choice for creating impactful and forward-looking Apple applications. The Swift community has also experienced substantial growth over the past few years.


The primary drawback of Swift mobile development is that occasionally, the project can lose its way, resulting in a poor quality user experience.

However, much like React Native, Swift is still relatively new, which can lead to a shortage of skilled professionals capable of implementing the entire tech stack using Swift.

React Native Vs. Swift Comparison

Let’s closely examine some key prospects of React Native and Swift to summarize the comparison.

1. Development Speed:

When comparing the development speed of React Native and Swift, Swift is notably faster for creating native iOS apps. It’s considered one of the simplest ways to make an iOS app compared to other frameworks. 

On the other side, React Native is a robust JavaScript framework primarily used for building web applications. Its development speed is decent but not as rapid as Swift’s in many cases.

2. Performance

In terms of performance, Swift generally outperforms React Native. However, Swift tends to use more CPU space and power while running an app. It supports high-quality graphical user interfaces (GUIs) that enhance the user experience and offer better performance. 

On the other hand, React Native’s compatibility with advanced GUIs is not as strong as Swift’s. To address this, developers often resort to different codebases, resources, and tools to tackle these issues.

3. User Interface

Since Swift is part of the iOS native language community, it seamlessly integrates with iOS design principles and takes full advantage of the latest user experience (UX) elements. However, developers need to fine-tune each coding section and component independently to achieve better optimization and performance.

Conversely, React Native relies on JavaScript as its core backend power and internal APIs to execute native components. It can adapt well to various screen sizes due to the implications of JavaScript web development. This allows React Native to present consistently on different screens and devices.

4. Learning Efficiency

In terms of learning, React Native stands out due to its integration with JavaScript, a well-established language that has been around for a long time. JavaScript is familiar to a vast number of developers worldwide, which means many of them already possess a strong grasp of it across various platforms. On the other hand, while Swift is also relatively accessible to learn, it can be harder to find experts in Swift compared to React Native.

5. Community & Support

In this comparison, React Native emerges as the clear frontrunner. Its extensive support is attributed to two main factors: the backing of Facebook (now Meta) and the widespread use of JavaScript. While Swift does have a dedicated community, it doesn’t match up to the level of support that React Native enjoys.

If you’re working on a project, regardless of its size or category, you’ll easily find React Native solutions. There are several tutorials, documentation, and guidance available on platforms like YouTube and React Native’s official website.

React Native Vs. Swift – Which option is best for iOS App development?

When comparing React Native and Swift for iOS app development, it’s important to consider your specific project needs, budget, and goals. Both options have their advantages, and the decision ultimately hinges on what aligns best with your requirements.

Swift is ideal for crafting iOS apps, ensuring a tailored and optimized experience within the iOS ecosystem. However, if your objective extends beyond iOS, React Native becomes an attractive option. It empowers you to concurrently create apps for both Android and iOS, delivering advantages in terms of cost, time, and developer availability.

In essence, both React Native and Swift have proven their mettle in delivering exceptional applications in their respective domains. Your decision should be rooted in your project’s unique requirements rather than solely following trends.
