GM release of Xcode 6 compile

Question

I just downloaded the GM release of Xcode 6 and it won\'t compile with this error:

Command /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault         


        

Answer 1

May be the same issue Swift compile error in XCode 6 GM

I had the same problem, then I use git checkout old versions to find which commit cause the problem, and try to find the key problem code. My key problem code is something like this

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

Other code could make the same problem, occur in Swift Optimization, and swift compiler doesn't tell you the exact location. This must be a bug by Apple.
