一年一度的苹果开发者大会于3日凌晨1点开幕，唯一的看点就是推出了"雨燕",其他无惊喜.

希望多大,失望就多大,颠覆性的产品在哪里?

苹果针对开发者推出了新的变成语言，“在过去的20年里，我们只支持Objective-C。”不过现在，苹果开发者平台支持新的变成语言：Swift。

Swift代表着迅速，时尚，安全和互动。与C语言和Python相比，“雨燕”更具优势。在同一款应用中，“雨燕”能够与C语言共存。在现场演示中，Swift的交互性更好：左侧输入代码，右侧就直接显示结果了。

就这样吧,不再跟踪了,去研究研究雨燕好了...

The Swift Programming Language

About Swift
Swift is a new programming language for iOS and OS X apps that builds on the best of C and Objective-C,without the constraints of C compatibility. Swift adopts safe programming patterns and adds mod more flexible,and more fun. Swift’s clean slate,backed by the mature and much-loved Cocoa and Cocoa Touch frameworks,is an opportunity to reimagine how software development works.
Swift has been years in the making. Apple laid the foundation for Swift by advancing our existing compiler,debugger,and framework infrastructure. We simplified memory management with Automatic Ref
built on the solid base of Foundation and Cocoa,has been modernized and standardized throughout. Objective-C itself has evolved to support blocks,collection literals,and modules,enabling framework a
without disruption. Thanks to this groundwork,we can now introduce a new language for the future of Apple software development.
Swift feels familiar to Objective-C developers. It adopts the readability of Objective-C’s named parameters and the power of Objective-C’s dynamic object model. It provides seamless access to existing C
interoperability with Objective-C code. Building from this common ground,Swift introduces many new features and unifies the procedural and object-oriented portions of the language.
Swift is friendly to new programmers. It is the first industrial-quality systems programming language that is as expressive and enjoyable as a scripting language. It supports playgrounds,an innovative fea
with Swift code and see the results immediately,without the overhead of building and running an app.
Swift combines the best in modern language thinking with wisdom from the wider Apple engineering culture. The compiler is optimized for performance,and the language is optimized for development,with
scale from “hello,world” to an entire operating system. All this makes Swift a sound future investment for developers and for Apple.
Swift is a fantastic way to write iOS and OS X apps,and will continue to evolve with new features and capabilities. Our goals for Swift are ambitious. We can’t wait to see what you create with it.
