React Native Vs. Swift: Best Path to iOS Development in 2024

React Native Vs Swift in 2024

Share This Post

Mobile applications are getting increasingly more sophisticated, feature-rich, and popular. There are almost 1.5 times as many applications available on the App Store compared to Google Play. This indicates a preference for developing iOS apps. The two most popular choices to develop iOS apps are JavaScript based React Native and Apple developed framework for iOS, Swift. To compare React Native Vs. Swift as a choice for iOS app development several factors driving the project like time to market, cost, developer skills, talent availability, app complexity, ease of future integrations needs to be accounted for. 


What is React Native?

React Native is a Javascript framework suitable for building applications for both android and iOS. The strength of React Native lies in its capability to support cross platform application development. With React Native developers can write reusable code for various platforms saving on development time and reduce cost. 


The React Native framework can be broken down into two key elements:


  • React: A popular JavaScript library that creates a smooth and responsive user interface for your app. Think of it as the blueprints for your app’s interactive elements, ensuring a delightful experience for your users.


  • Native: A component library that provides the necessary elements like buttons, menus, and animations to help it seamlessly integrate with the Android or iOS environment. 


Benefits of React Native

React Native presents a strong case for its adoption in various circumstances.


Extensive Documentation and Developer Pool: JavaScript the foundational language behind React Native is the most popular language and has a wide pool of talent. This has also helped in creating detailed documentation over the years. 


Cross-Platform Development and Code Reusability: React Native can be versatile used for both iOS and Android applications upon a single codebase. This maximizes code reusability, saves cost, and reduces time to market. 


Developer-Friendly Features: Developers appreciate React Native for its speed, particularly when handling network data. Its modular system allows for clean and efficient construction of applications by assembling independent modules. Moreover, the hot reloading feature enables instant updates upon code changes, eliminating the need for project recompilation, further increasing development speed.


Trade-offs for Complex Tasks: However, where complex graphics or processing of large datasets are involved, Swift may outshine React Native. Its native nature offers potential performance advantages in such scenarios.


What is Swift?

Swift, an Apple-born programming language introduced in 2014, emerged as the successor to Apple’s previous language, Objective-C. Developers favor Swift due to its intuitive nature, aligning well with Apple’s ethos.


One notable feature is its Automatic Reference Counting (ARC), offering convenient memory management. Unlike having a singular “progenitor,” Swift amalgamates elements from various languages like Object-C, Haskell, Python, C#, CLU, and more.


Swift is predominantly used in macOS, iOS, iPadOS, watchOS, and tvOS app development, although Swift extends its reach to Windows and Linux platforms. Its LLVM compiler technology fosters rapid and efficient code writing. Notably, Swift undergoes continuous updates and evolution to stay at the forefront of programming languages.


Benefits of Swift

While not a one-size-fits-all solution, Swift offers compelling advantages in specific scenarios:


Native Performance and Hardware Access: As a native iOS language, Swift seamlessly integrates with Apple hardware and leverages the full potential of the iOS user interface. This makes it the clear winner for apps requiring low-level access to specific hardware resources, such as high-performance sensors or custom hardware features.


Security and Data Protection: Swift is designed with security and data protection in mind, minimizing vulnerabilities compared to other languages. This makes it the preferred choice for sensitive applications like financial or payment apps where security is paramount.


Superior Performance for Demanding Tasks: When dealing with large datasets, complex graphics, or computationally intensive tasks, Swift’s native optimization often outperforms cross-platform frameworks like React Native. This can be crucial for high-performance apps or those with demanding visuals.


However, Swift also presents some drawbacks:


Cost of Development: Due to its relative exclusivity to iOS, finding Swift developers can be more expensive than those adept in more widespread languages like JavaScript. This makes Swift less cost-effective if iOS is not the primary platform for your application.


Limited Platform Reach: Unlike cross-platform options, Swift development only targets iOS. This becomes a disadvantage if your target audience extends beyond Apple devices or if Android compatibility is desired.


React Native Vs. Swift: Which Framework Is Better? 

React Native Vs. Swift: Performance

React Native wins over Swift in memory usage and GPU speed. React Native allows seamless integration of native code modules, leveraging platform-specific features and potentially boosting performance for specific tasks. Additionally, its ecosystem boasts many tools for optimizing app performance.


React Native Vs. Swift: User Interface

Swift was made for the iOS ecosystem therefore it can use iOS components to create beautiful UIs and visually appealing apps. React Native uses native components and APIs and allows building native-like applications that look and seem very close to native. Clearly Swift offers a far beautiful UI.


React Native Vs. Swift: Stability

Though React Native can generate a UI resembling native apps, it doesn’t match the stability found in Swift. The primary focus of React Native is to utilize internal APIs and libraries to execute applications smoothly. This means there could be many layers in the development process, making the application a bit unstable. Opting for the native development language allows for harnessing device features, resulting in a more stable, feature-rich app.


React Native Vs. Swift: Speed of Development

Backed by the well-established JavaScript, React Native offers a familiar syntax and abundant learning resources. This makes it easier for developers, especially those already comfortable with JavaScript, to pick up and quickly create codebases. The vast ecosystem of tools surrounding React Native empowers developers with everything they need, from code editors and testing frameworks to UI libraries and performance optimization tools. Clearly it is less time consuming to churn applications using React Native.


React Native Vs. Swift: Learning Curve

When venturing into mobile app development, choosing the right framework is crucial. Both React Native and Swift offer compelling options, but navigating their learning curves can pose different challenges. Developers accustomed to web development might find React Native’s JavaScript base surprisingly comfortable. However, the transition to app development can introduce unfamiliar territory, prompting a sense of unease. 


Compared to React Native, Swift presents a steeper learning curve, particularly for those without prior programming experience. Its syntax and concepts can feel distinctly different from web development paradigms. However, Apple provides extensive official documentation and interactive learning tools like Swift Playgrounds. These resources can dramatically ease the learning process, even for individuals with no prior technical background.


React Native Vs. Swift: Talent Availability

Even though it’s difficult to compare the two because React Native is a framework and Swift is a language, it’s clear that React Native has a far larger community. On the other hand, Swift has shown to be quite popular in the mobile app development industry and has been rising in popularity over time.



In the realm of iOS application development, both React Native and Swift stand as commendable tools, each with its distinct strengths. Determining the best fit for your project requires weighing their differences. React Native facilitates the creation of iOS, Android, and web apps through a unified code base, offering cost-effectiveness without compromising quality.  On the other hand, Swift emerges as a robust and user-friendly language, ideal for large-scale enterprise applications. Its efficiency surpasses React Native in building iOS apps, ensuring clean code, superior user experiences, and seamless performance. Swift’s forte lies in native iOS app development, excelling particularly in this domain. Selecting between the two hinges on aligning their unique capabilities with the specific requirements of your project.
