I have Xcode 6.4 installed and I also have Xcode 7 beta installed. Recently I launched Xcode 6 and I showed multiple versions of the iOS simulators and they had long id/like uuid looking ids in the names. Some of them do not work. Has anyone seen this and does anyone have an idea of how to fix it. I have deleted beta. I have deleted and reinstalled Xcode 6 multiple times. I have uninstalled Xcode
