Impossible "paid load". Give NoneType Error

Question

Trying to use apportable for the first time. Keep getting this error:

TypeError: 'NoneType' object is not subscriptable 

and

 NSUnderlyingError = "Error Domain=NSPOSIXErrorDomain Code=2 \"The operation couldn\U2019t be completed. No such file or directory\""; 

And then the script ends.

Answer 1

 xcode-select --switch /Applications/Xcode.app/Contents/Developer 

Background: this can happen if you upgraded to Xcode 5. It seems that Xcode 5 has an error that it may generate incorrect output when xcodebuild starts.
