问题 After upgrading to XCode 6.0.1, in In House Enterprise Distribution from Archive now creates a .pkg file instead of .ipa/.plist files. This breaks our enterprise distribution system.

This is frustrating because I have to manually remove one of them every time. Is there a way to change this? 回答1: If your swift files contain Unicode characters, auto completion will fail even if the characters are comments.
