iOS apps are applications that run on Apple's mobile operating system, iOS, which powers devices such as iPhone, iPad, iPod touch, Apple Watch, and Apple TV. iOS apps can be written in JavaScript using the React Native framework, or in one of the two primary programming languages, Swift or Objective-C.
Swift: Swift is the most popular and recommended language for iOS app development. It was introduced by Apple in 2014 as a replacement for Objective-C and ever since it has been widely used by iOS developers. Swift is a modern, fast, safe, and expressive language that offers many features that make iOS development easier and more enjoyable.
Objective-C: Objective-C is the oldest and most established language for iOS app development. It was created in 1984 as an extension of C with object-oriented features. It was adopted by Apple in 1988 as the main language for its NeXTSTEP operating system, which later became the foundation for macOS and iOS. Objective-C is a powerful, dynamic, and flexible language that has been used to build many successful iOS apps.
JavaScript: JavaScript is a scripting language that was originally designed for web development but has also been used for mobile development with the help of frameworks such as React Native. React Native is an open-source framework created by Facebook in 2015 that allows developers to use JavaScript to create native iOS apps. React Native uses a JavaScript engine to run JavaScript code on the device and a bridge to communicate with native components. React Native also uses React, a library for building user interfaces with reusable components.
Flutter: Flutter is a cross-platform framework that was created by Google in 2017 that allows developers to use Dart, a programming language developed by Google, to create native iOS apps. Flutter uses a Skia graphics engine to render its own widgets instead of using native components. Flutter also uses a reactive programming model that updates the UI based on state changes.
Xamarin: Xamarin is a cross-platform framework that was created by Microsoft in 2011 that allows developers to use C#, a programming language developed by Microsoft, to create native iOS apps. Xamarin uses a Mono runtime to run C# code on the device and a binding layer to communicate with native components. Xamarin also uses .NET, a software framework developed by Microsoft, to provide various functionalities and services.
