Apple Swift: General-Purpose Programming Language for iOS and OS X Developments
Swift is a general-purpose, multi-paradigm, compiled programming language developed by Apple Inc., making iOS and OS X development faster and easier through features like type safety, type inference and fast compilation.
What is Apple Swift?
Swift is a general-purpose, multi-paradigm, compiled programming language developed by Apple Inc. It was first released in 2014 as the successor to Objective-C for Apple's iOS, macOS, watchOS, and tvOS operating systems. Some key features and characteristics of Swift include:
- Fast and efficient: Swift code compiles extremely quickly and the resulting apps have high performance. The compiler uses advanced optimizations to generate efficient machine code.
- Safe: Swift is designed for safety and avoids entire classes of common programming errors like null pointer exceptions.
- Modern syntax: Swift has an easy-to-read and learn syntax with many modern features inspired by languages like Python and Rust.
- Open source: After being proprietary for some years, Swift is now open source with a community-driven development model.
- Cross-platform capabilities: Swift can be used to create apps for iOS, macOS, watchOS and tvOS. It can also be deployed on Linux servers.
- Seamless Objective-C interoperability: Swift works side-by-side with Objective-C and frameworks written in Objective-C can be imported and utilized in Swift.
With its combination of simplicity, performance, safety and power, Swift has quickly become one of the most widely adopted languages for iOS and macOS development.
