Build apps using a powerful open language.
- Xcode 6.0.1+
- Swift Standard Library
Swift includes modern features like type inference, optionals, and closures, which make the syntax concise yet expressive. Swift ensures your code is fast and efficient, while its memory safety and native error handling make the language safe by design. Writing Swift code is interactive and fun in Swift Playgrounds, playgrounds in Xcode, and REPL.
If you're new to Swift, read The Swift Programming Language for a quick tour, a comprehensive language guide, and a full reference manual. If you're new to programming, check out Swift Playgrounds on iPad.
