我已升级到Xcode 7，我的项目升级到Swift2。我的项目是ObjC和Swift代码的混合体。我也升级到可可豆荚0.38.2。升级后，项目编译失败。具体来说，编译失败并出现以下错误：
Command /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/swiftc failed with exit code 1
我已将此问题跟踪到以下消息：
MergeSwiftModule normal x86_64 /Users/murdockcrc/repos/HdV%20-%20iOS/Build/Intermediates/Pods.build/Debug-iphonesimulator/SwiftyJSON.build/Objects-normal/x86_64/SwiftyJSON.swiftmodule
which fails with the following error:
<unknown>:0: error: error opening '/Users/murdockcrc/repos/HdV%20-%20iOS/Build/Intermediates/Pods.build/Debug-iphonesimulator/SwiftyJSON.build/Objects-normal/x86_64/SwiftyJSON-Swift.h' for output: No such file or directory
该问题仅与SwiftyJSON无关。即使我删除了这个库，我的另一个Swift依赖项也会因同样的错误而失败。
我对cocoa pod与框架和混合objc-swift项目的工作方式并不了解，但我认为伞标题有问题，并且swift编译器可以访问依赖项。
这是我的podfile
