swift - Carthage + Quick 框架 + Swift 2 = "error: module file was created by an older version of the compiler; rebuild ' Quick'，然后重试”

Question

我将 Xcode 7 beta 5(这是当前安装的唯一 xcode)与 Swift 2 一起使用，当我尝试使用 Quick 运行单元测试时，出现以下错误:

error: module file was created by an older version of the compiler; rebuild 'Quick' and try again

我正在使用 Carthage (0.8.0) 来管理我的依赖项。我的 Cartfile.private 有:

github "Quick/Quick" ~> 0.5.0
github "Quick/Nimble" "v2.0.0-rc.2"

据我所知，这些是这些库的 Swift 2 版本。我链接了库，当我尝试运行单元测试时，我收到了指出的错误。

这里有一个类似的问题，但这似乎不是我的问题 Realm: Module was created by an older version of compiler and could not build objective-c module

我已经清理了 DerivedData 和 Carthage/Build 文件夹，但仍然没有成功。

如何使用 Swift 2 和 Quick 运行单元测试？

如果您从其他测试版更新，可能与以下问题有关:https://github.com/neonichu/xcode-install/issues/48

xcode-install uses ditto to install Xcode, which merges files from the source into existing directories at the destination path.

If a new (beta) version of Xcode doesn't contain files which were present in the previous version, the old files will still be there after installing the update.

尝试卸载并重新安装 Xcode。
