I use Xcode for iOS Development. I had Alcatraz plugin and some another formatting plugins installed on my Xcode 6.1. After updating IDE to 6.3 they are disappeared. Also I've got new simulators iOS 8.3 but I want still use iOS 8.1, 8.0 and even 7.1, 7.0 too. They were installed but now they are not. I have downloaded all data back manually but there are new updates at this moment, Xcode 7 is coming.
Was it a Xcode bug or it's normal? If there a way to keep plugins and simulators after update?
