Swift is a modern programming language developed by Apple, designed to be fast, safe, and expressive. It was introduced to simplify the process of writing software and is now used in almost 1 million apps. Swift is not only ideal for app development but is also used throughout Apple's software stack, including apps, system services, frameworks, firmware, and network services.

Swift's key features include:

  • Safety: Swift is designed to eliminate common programming errors and improve code safety.
  • Speed: It is optimized for performance, making it suitable for even the most performance-sensitive and secure code.
  • Approachability: Swift's syntax is lightweight and easy to learn, making it accessible for newcomers while being powerful enough for experts.
  • Interoperability: Swift has built-in interoperability with C and C++, allowing it to be used alongside existing codebases.

Swift has evolved significantly since its introduction, with major milestones including the introduction of the Swift Package Manager, the stable ABI on Apple platforms, and the concurrency model with async/await and actors. The latest version, Swift 6, introduces data race safety and a new language subset called embedded Swift for highly constrained systems.
