To enable this, make sure XCode is not running and run the following script in the terminal:
defaults write com.apple.dt.Xcode ShowDVTDebugMenu -bool YES sudo mkdir -p /Applications/Xcode.app/Contents/Developer/AppleInternal/Library/Xcode sudo touch /Applications/Xcode.app/Contents/Developer/AppleInternal/Library/Xcode/AppleInternal.plist
Then boot XCode back to see a menu that allows one to see performance metrics and test the user interface.
