What is Swift?

Swift is a compiled programming language that was created by Apple specifically for developing native iOS applications. The language is only 7 years old but has already gained a lot of traction in mobile app development. Companies that previously used Objective-C for their app development switched to Swift to take advantage of its flexibility, conciseness, and simplicity.

The main goal of creating Swift was to attract more developers into development for iOS and macOS. As Objective-C is quite complicated, Swift is much simpler and enables developers to utilize native hardware features and build feature dense and high-quality applications. Leveraging the capabilities of Apple software allows companies to build more advanced solutions using camera, GPS, Bluetooth, etc.

Benefits of Swift

Why have companies switched to Swift to build iOS applications? What makes it such a popular choice in the mobile development arena?



The official Apple website claimed that Swift is 2.6 times faster than its predecessor, Objective-C. Swift has a simple syntax and employs the LLVM tool to compile the code directly to the machine code. As the name of the language suggests, building an app with Swift accelerates the development processes.



The syntax of the language is simpler and easier to grasp, which makes it a more readable technology when compared to others. Developers also need fewer code lines to produce a functional application, thus shortening the time to market.



Swift mobile development is less error-prone as it comes with type-safe features. This lets developers catch potential errors in code while typing and prevents them from bringing mistakes to code execution. On top of that, Swift automatically defines all memory accesses, thus protecting the program from crashing.

ABI stability

ABI (Application Binary Interface) stability came into effect with the Swift 5 version of the language and solved a major issue. Without this feature, every time a new version of the language was launched and developers tried to implement it into the existing application, some features crashed. ABI stability prevents this from happening, and ensures that all language versions are compatible with each other.


User experience

Being lighter, Swift written applications take less time to install and require less memory storage on the device. The language is also specifically created for native iOS development, and it gives more access to the native device’s features. As a result, you can build apps that look and perform better, and attract more users.



What is the difference between Xcode and Swift? The latter is a programming language while the former is an IDE that helps you create great applications. Using Swift for iOS native app development gives access to Xcode. Working together, these technologies allow you to build apps for macOS, tvOS, watchOS, and iOS. You can even create applications for Linux and Windows and expand your target audience.


Drawbacks of Swift

Does Swift have any serious disadvantages that you should know of? How do they affect the development process and user experience?

Being a relatively new technology, Swift has a long way to go in building a strong community and developing helpful libraries and packages. However, the language has already gained a lot of attention from the mobile app development community and is considered one of the best languages for app development. At the same time, if you choose to go with Swift, you might need to spend more time finding seasoned professionals, especially if we compare React Native vs Swift.

What is React Native?

react native vs swift react native stats

React Native is a JavaScript framework created by the Facebook team to accelerate mobile development processes and build apps across platforms. In Swift vs React Native, the latter is supported by JavaScript which is the most popular language in the world, according to Statista. With almost 68% of developers’ support, JavaScript is way ahead of Swift in popularity and usage.

Besides, building cross-platform programs is more cost and time efficient, and allows you to penetrate the market sooner. On the other hand, platform independent apps tend to be less powerful and present a poorer user experience. Let’s talk about React Native’s benefits and drawbacks in more detail before investigating the main differences between React Native vs Swift.


Benefits of React Native

How easy is it to build a React Native iOS app, and what are the functions of the framework that make the development faster?


Time efficiency

As already mentioned, React Native is operating system independent, which significantly reduces the development cycle and time to market. This is achieved by writing one code and deploying it to both platforms with a few native tweaks.


Smaller team

Building one program for both iOS and Android allows you to have one JavaScript team on staff instead of having two native development teams. You will also avoid timeline discrepancies that often occur when you have two teams developing two applications at the same time. Finally, having one single team doing all the work prevents issues that occur when one of the developers calls in sick since his or her teammates can easily pick up the slack.


Rich library support

According to nmpJS, React Native has nearly 33,000 libraries and packages, while a similar search engine on the Swift website shows only 3,800 packages. Certainly, the number alone does not guarantee the quality of the language or framework, however, it does prove the community’s commitment and enthusiasm to contribute. For any technology, this commitment is crucial for further development.


High grade of automation

The process of software development does not end with writing code, but extends to testing, releasing, bug fixing, etc. Developers prefer to automate these tasks to accelerate the process and to avoid routine. React Native allows you to delegate mundane tasks to third-party services like Bitrise, AppCenter, Amplify, and others.


Gateway to nativeness

Although you cannot build a 100% native to iOS React Native iPhone app, you can create some parts of the app using this cross-platform technology and save costs. In other words, you can build crucial parts using native tools and less performance affecting features with React Native. This way, you can deliver a cost-effective native application in a shorter amount of time.


Drawbacks of React Native


Cross-platform solutions always lose to native apps when it comes to performance and speed. React Native applications take up more space on the device and on average create a worse user experience for your customers. However, this issue becomes relevant only if you talk about high dynamic products like games.


Longer testing process

Although creating applications with React Native speeds up the process due to a single code source, the process of testing takes up more time when comparing React Native vs Swift. React Native apps require more time and precision when it comes to running tests, as errors are likely to appear on both platforms.

React Native vs Swift for iOS: Features, Industries, and Types of Apps

react native vs swift

Knowing the weaknesses and strengths of native and cross-platform mobile development as well as that of Swift and React Native iOS development, let’s see which technology suits your project.


React Native vs Swift: Comparison


User Interface

React Native uses native components and APIs and allows building native-like applications that look and seem very close to native. Swift was built exclusively for native iOS development which guarantees top-notch UI elements for iOS devices.

React Native vs Swift UI: Swift wins.


While React Native can deliver a decent native like UI, it cannot reach the same amount of stability when compared to Swift. Using native development language, you can leverage the device’s features and build a more stable and feature-rich application.

React Native vs Swift stability: Swift wins


Here too, Swift takes the lead, as native development almost always provides superior performance over cross-platform development. Especially when it comes to dynamic and graphic effects-dense applications, Swift is way ahead of the competition.

React Native vs Swift performance: Swift wins

Coding speed

Coding speed really depends on your goals. If you are developing an application only for iOS, then Swift is definitely your choice. However, if you would like to launch your solution on both iOS and Android, React Native will guarantee faster results.

Talent pool

Although it is hard to compare these as React Native is a framework and Swift is a language, one can still conclude that React Native has a much bigger community. But Swift has proven to be very popular and useful among the mobile app development community, and has been gaining more and more attention over time.

React Native vs Swift talent pool: React Native wins

Development costs

Swift developers’ rates on average are higher than rates of JavaScript coders. While we will talk about the costs in detail in the next part, the average numbers for developers look like the following:

The US: Swift developers - $75-110 and $40-65 in Eastern Europe

React Native coders in the US - $70-110 and $35-60 - in Eastern Europe.

The difference is negligible, however, React Native development cycle is usually shorter as it delivers two applications with one code, which makes it overall a cheaper option.

React Native vs Swift development costs: React Native wins

Learning curve

React Native is a framework that supports JavaScript - the most used language. As already mentioned, 68% of developers employ JS for their coding, which means that these developers can easily adapt React Native in their work. Swift, on the other hand, is quite easy to learn, but it still requires a learning curve.

React Native vs Swift learning curve: React Native wins


Since both tools were developed by well-respected and seasoned tech giants - Facebook and Apple, both React Native and Swift have excellent documentation.
