XCode version - 6 GM (It's a latest stable version). Somebody know how fix this issue?

Answer 1

I found solution, but it's not a best way. After reinstall XCode this issue was fixed.

Answer 2

Did you try removing your project folder in the DerivedData folder before reinstalling xCode?

I had the same problem updating from beta 6 to beta 7, and that solved the problem.

Answer 3

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.
