“End-of-central-directory signature not found.” when installing Xcode 8 beta xip file
The .xip file format contains an archive (xar containing a gzip archive and metadata) and a signature of the archive.

So instead of overriding it with a func declaration as you’ve done, you override the getter with a var declaration: override var preferredStatusBarStyle: UIStatusBarStyle { return .lightContent } The Swift compiler’s error message here could probably be better — since it seems to know your … Read more
