1、打开终端，输入以下代码：
defaults read /Applications/Xcode.app/Contents/Info DVTPlugInCompatibilityUUID
2、获取到DVTPlugInCompatibilityUUID，然后
find ~/Library/Application\ Support/Developer/Shared/Xcode/Plug-ins -name Info.plist -maxdepth 3 | xargs -I{} defaults write {} DVTPlugInCompatibilityUUIDs -array-add 9F75337B-21B4-4ADC-B558-F9CADF7073A7
3、重启xcode
4、跟以前一样，打开相应插件，运行，退出，再重启xcode，OK了！
