After the upgrade of Xcode, all kinds of god plug-ins are not good to use, in the case of no misoperation to join the blacklist, enter the following code in the terminal, more efficient solution to the problem of plug-in is not good to use.
Enter in terminal
// Get the UUID of the current version of Xcode
defaults read /Applications/Xcode.app/Contents/Info DVTPlugInCompatibilityUUID
/ / find all installed plug-ins (not join blacklist), will all plug-ins UUID replace version of Xcode UUID now, will replace ChengGangGang XXXX get DVTPlugInCompatibilityUUID.
find ~/Library/Application\ Support/Developer/Shared/Xcode/Plug-ins -name Info.plist -maxdepth 3 | xargs -I{} defaults write {} DVTPlugInCompatibilityUUIDs -array-add XXXX
The slow way is to find the plug-in folder of Xcode, select “open package content” of the plug-in, and replace all UUID of the plist file in it with the one obtained just now. I do not recommend using it, and I will not repeat it here.
If you are unlucky enough to click join blacklist, enter:
Sudo open/Users/username/Library/Application/Support/Developer/Shared/Xcode/plug-ins
Find the folder of plug-ins, directly delete the plug-ins that were added to the blacklist, reinstall, it is ok.
