导读：从去年年底至今，全球iOS开发者一直在期待以及展望Swift 3，在凌晨“开放”成重点的WWDC上，苹果实现了Siri、iMessage等软件在多平台的打通及开放，而对于开发者而言，最为关注的莫过于Xcode和Swift的更新。

北京时间6月14日，苹果开源语言的高级经理Ted Kremenek在Swift官方博客上发布了一篇题为“Swift 3.0 Preview 1 Released!”的文章，介绍了Swift 3.0的第一个开发者预览版：

正如Swift 3.0发布流程中提到的那样，新的3.0开发者预览版（包括seed或beta版）提供了合格的Swift 3 build包，而不仅是抓取master分支（即tip-of-trunk开发）上的最新快照，这种方式所提供的Swift库更为稳定。

目前Swift 3的所有开发者预览版都还处于开发阶段，若非特别注明，都不是Swift 3的最终版。

下面列出了本次在Swift 3.0开发者预览版第一版中所实现的Swift改进提案，此前为大家关注的几项变动也在其中：

SE-0002: 删除currying func声明语法 SE-0003: 函数参数中不再使用var关键字 SE-0004: 删除++与–操作符 SE-0005: 将Objective-C的API更好地接入Swift中 SE-0006: 将API指南应用于标准库中 SE-0007: 移除了C语言风格的for循环（条件与增量下） SE-0008: 为可选序列增加一个Lazy flatMap SE-0019: Swift测试 SE-0023: API设计指南 SE-0028: 更新Swift的debug标识符（如__FILE__等） SE-0048: 泛型类型别名 SE-0049: 将声明式@noescape与@autoclosure改为类型属性
