Xcode swift failed with exit code 254

Question

I am getting this compiler error in my code and I can\'t figure out why:

:0: error: unable to execute command: Segmentation fault: 11


        

Answer 1

I was getting the same error and I tracked it down to this: I was extending NSError and in the extension was defining an enum. Moving the enum definition out of the extension fixed the error.

extension NSError {
    enum WYBErrorCodes: Int {
        case Fatal = 1000
        case XmlParse = 1100
        case CoreData = 1200
    }

    [...]
}
