Swift Programming Language

Swift is a multi-paradigm, general-purpose, open-source programming language for iPadOS, macOS, tvOS, watchOS, and iOS development. It was created by Apple in 2014 to give developers a powerful language to develop iOS apps. According to swift.org, the language was designed to be safe, fast, and expressive. It's intended to be a replacement for C-based languages. The Swift language is constantly evolving, and the community continues to grow. Swift source code can be found on GitHub, making it easy for anyone to access the code.

Swift features

Powerful generics: Generics allow you to write flexible, reusable functions and types that can work with any type.
Native error handling: Swift provides support for throwing, catching, propagating, and manipulating errors at runtime.
Structs and classes: Swift allows you to define a structure or class in a single file, and the external interface is made available for other code to use.
Protocol extensions: Swift allows you to define behavior on protocols themselves, rather than in global functions or individual conformances.
Memory safety: Swift automatically manages memory and prevents unsafe behavior from happening in your code.
Memory management: With Automatic Reference Counting (ARC), Swift tracks and manages our app's memory usage. This means we don't need to worry about memory management ourselves.
Flexible enumerations: Swift enums support pattern matching and can have payloads.
Swift was designed to be easy to learn and easy to use. Apple created the language with new coders in mind. Whether you're still in school, exploring a new career path, or wanting to learn how to code, Swift was created to be a simple and intuitive first language to learn.

Once you learn Swift, you'll be an appealing candidate for potential employers. Swift developers are in high demand. According to Apple, the company has created around two million jobs in the United States. According to Indeed, the average salary for an iOS developer in the U.S. is $116,804. If you want to get into app development, Swift is a smart language to learn.
