Today's upgrade of Xcode to 6.4 was not available before the plugin was installed. Here's a solution:
The steps are as follows:
First, see the UUID of Xcode
Perform defaults read/applications/xcode.app/contents/info Dvtplugincompatibilityuuid in terminal
Copy the string after the UUID
Then open the directory where the Xcode plugin is located: ~/library/application support/developer/shared/xcode/plug-ins;
Select the installed plug-in such as Vvdocumenter-xcode, right-click "Show Package Contents";
Locate the Info.plist file, locate the Dvtplugincompatibilityuuids item, add a Item,value value for the previous Xcode uuid, save.
After you restart Xcode 6, you will be prompted for "load bundle", "Skip bundle" When you restart Xcode, and you must select "Load Bundle", otherwise the plugin cannot be used.
What if the hand hits the "Skip Bundle" swelling?
Locate the plug-in installation path, continue to open in Info.plist delete the last and the command side of the same UUID number, usually will be the last line, you add the line to be deleted
Restart Xcode after saving
Add the previous Xcodeuuid again. Plugin prompt reappears on reboot
"Go" xcode up to 6.4 plugin invalidation, with add plugin accidentally click Skip Bundle solution
