When it comes to developing an iOS app, choosing the right programming language is crucial. There are several options available, but some are more suited for iOS development than others. In this article, we will explore the best programming language for iOS app development and discuss their pros and cons.

1. Swift

Swift is a powerful and intuitive programming language developed by Apple specifically for iOS, macOS, watchOS, and tvOS app development. It was introduced in 2014 and has gained popularity among developers for its simplicity and efficiency.


  • Easy to Learn: Swift has a clean and concise syntax, making it easier for beginners to understand and learn.
  • Safe and Secure: Swift eliminates common programming errors by enforcing stricter rules and providing better memory management.
  • Fast Performance: Swift is designed to be fast and efficient, resulting in better app performance.
  • Interactive Playground: Swift offers an interactive playground where developers can experiment and see the results in real-time.
  • Backward Compatibility: Swift is backward compatible with Objective-C, allowing developers to integrate existing code into new Swift projects.


  • Less Third-Party Libraries: Swift is a relatively new language, so it has fewer third-party libraries and resources compared to Objective-C.
  • Compatibility: While Swift is backward compatible, there might be some compatibility issues when working with older iOS versions.
  • Learning Curve for Objective-C Developers: Objective-C developers may need some time to adapt to the syntax and concepts of Swift.

2. Objective-C

Objective-C is an object-oriented programming language that has been used for iOS app development for many years. It was the primary language for iOS development before the introduction of Swift.


  • Large Community: Objective-C has been around for a long time, resulting in a large and active community of developers who can provide support and resources.
  • Extensive Libraries: Objective-C has a vast collection of third-party libraries and frameworks, making it easier to find pre-built solutions for various functionalities.
  • Compatibility: Objective-C is compatible with older iOS versions, ensuring that apps built with it can run on a wide range of devices.
  • Legacy Codebase: Many existing iOS apps are written in Objective-C, so having knowledge of the language allows developers to maintain and update those apps.


  • Complex Syntax: Objective-C has a more complex and verbose syntax compared to Swift, which can make it harder to learn and read.
  • Memory Management: Objective-C uses manual memory management, which can be error-prone and time-consuming.
  • Less Secure: Objective-C is more susceptible to common programming errors and memory-related issues.

3. React Native

React Native is a JavaScript framework developed by Facebook that allows developers to build native mobile apps using JavaScript. It is not a programming language itself, but it is worth mentioning as an alternative for iOS app development.


  • Code Reusability: With React Native, developers can write code once and use it for both iOS and Android platforms, saving time and effort.
  • Fast Development: React Native offers a hot-reloading feature, allowing developers to see the changes in real-time without recompiling the entire app.
  • Large Developer Community: React Native has a large and active developer community, providing support and a wide range of pre-built components.
  • Native Performance: React Native apps have near-native performance as they are compiled into native code.


  • JavaScript Limitations: React Native relies on JavaScript, which may not be as performant as native code for certain complex functionalities.
  • Platform Limitations: Although React Native allows code reusability, there might be some platform-specific limitations or inconsistencies.
  • Dependency on Native Code: Some functionalities may require writing native code modules, which adds complexity to the development process.


Choosing the best programming language for iOS app development depends on various factors such as project requirements, developer expertise, and performance considerations. Swift is the recommended language for iOS app development due to its ease of use, safety features, and performance. However, Objective-C still has its advantages, especially when working with legacy code or utilizing extensive third-party libraries. React Native is a viable option for cross-platform development but may have limitations for certain functionalities.

Ultimately, the choice of programming language should be based on careful consideration of the project’s specific needs and the developer’s familiarity with the language. Whichever language you choose, iOS app development offers exciting opportunities to create innovative and user-friendly applications for the ever-growing Apple ecosystem.
