"Компания Apple представила основанный на LLVM язык программи..." Отправлено Stax, 03-Июн-14 14:38
Краткий список возможностей/особенностей: http://www.reddit.com/r/programming/comments/274t5s/apple_sw... Statically typed with type inference. Generics. Closures. No exceptions. Extension methods. Properties (syntax similar to C#), including lazy properties with the "@lazy" annotation. Functions, methods and type (static) methods. Support for observers (with "willSet" and "didSet"). Interesting to see the observer pattern baked in a language although I'm more partial to event buses for this kind of thing. Enums. Classes and structures (structures have restrictions regarding inheritance and other things). For and while loops (statements, not expressions). "mutating" keyword. Named parameters. Deinitializers (finalizers). Protocols (interfaces). Optional chaining with "a?.b?.c" and forced dereference with "!."". Convenient "assign and test": "if let person = findPerson() ...". Type casting with "is", down casting with "as?" (combines nicely with the "let" syntax. Ceylon does it right too).
