Friends, after upgrading Xcode7, some plugins cannot be used. Now the following solutions are provided:
1. First check the UUID of Xcode and execute it in the terminal
defaults read /Applications/Xcode.app/Contents/Info DVTPlugInCompatibilityUUID
will get a string of UUID codes
2. Find the directory where the Xcode plugin is located
~/Library/Application Support/Developer/Shared/Xcode/Plug-ins
Select an installed plug-in such as: VVDocumenter-Xcode, right-click to display the package content, and find info.plist
Find the item of DVTPlugInCompatibilityUUIDs, add an Item, the value of Value is the UUID of the previous Xcode, save.
After restarting Xcode, it will prompt "Load bundle" and "Skip Bundle", here you must select "Load bundle", otherwise the plugin will not be available.
3. Solution if you click "Skip Bundle" by mistake
Find the plugin installation path, continue to open info.plist and delete the same UUID number as in the command side, usually the last line, and the line you added should also be deleted
Restart Xcode after saving
Add the previous xcodeUUID again. After restarting, the plugin prompt appears again
