XCode 6 GM中的Swift编译错误

Question

我正在使用一种新的Swift语言来开发IOS应用程序。 突然我从我的XCode中得到了一个错误。

Command /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/swiftc failed with exit code 1

XCode版本-6 GM（这是最新的稳定版本）。 有人知道如何解决此问题？

Answer 1

在重新安装xCode之前，是否尝试删除DerivedData文件夹中的项目文件夹？

从Beta 6升级到Beta 7时，我遇到了同样的问题，从而解决了该问题。

Answer 2

我找到了解决方案，但这不是最佳方法。 重新安装XCode之后，此问题已修复。

Answer 3

我遇到了同样的问题，然后我使用旧版本的git checkout查找导致该问题的提交，然后尝试查找关键问题代码。 我的关键问题代码是这样的

func afunc() {
    class AClass() {
    }
    let ac = AClass()
    //....
}

其他代码可能会引起同样的问题，发生在Swift优化中，而swift编译器不会告诉您确切的位置。 这一定是Apple的错误。
