What Language iOS Apps are Written In?
As of 2022, the most popular programming languages used to develop iOS apps are Swift, Objective-C, and Swift UI.
What is Swift?
- Developed by Apple, Swift is a modern, high-performance, and safe language designed specifically for building iOS, macOS, watchOS, and tvOS apps.
- Swift is highly object-oriented, statically typed, and dynamically typed, which makes it easy to learn and use.
- It has been chosen as the default language for iOS and macOS app development since 2014.
- Swift is progressively trying to phase out Objective-C, which was the original language for iOS app development.
What is Objective-C?
- Developed by Apple in 2001, Objective-C is a stated-based language that is still used for developing iOS, macOS, watchOS, and tvOS apps.
- Objective-C is old school, virtual procedure call-based, and statically typed, which makes it slower and more complex to learn and use.
- It has been officially deprecated by Apple since 2015 and is being replaced by Swift.
- Although Objective-C is still widely used, Swift is rapidly gaining popularity among developers due to its modern design and better performance.
What is Swift UI?
- Developed by Apple in 2019, Swift UI is a UI framework that allows developers to create iOS, macOS, watchOS, and tvOS apps with a more modern and intuitive API.
- Swift UI is completely built on top of Swift, which means it doesn’t require any additional dependencies or frameworks.
- It has been designed to provide a more modern and simplified way of building user interfaces, making it easier for developers to create complex and beautiful interfaces.
- Swift UI is hugely expanding the capabilities of the Xcode IDE, allowing developers to create apps with a more native look and feel.
Other Languages Used in iOS App Development
- While Swift, Objective-C, and Swift UI are the most popular languages used in iOS app development, other languages are also used in certain cases:
- Arabic: Many Arabic-language apps are developed using Swift, due to Apple’s official Arabic support for iOS.
- Korean: Some Korean-language apps are developed using Swift, due to Apple’s Korean support for iOS.
- Russian: Many Russian-language apps are developed using Swift, due to Apple’s Russian support for iOS.
- Latin American Spanish: Some Latin American Spanish-language apps are developed using Swift, due to Apple’s Latin American support for iOS.
