1.移除之前的Alcatraz插件

rm -rf ~/Library/Application\ Support/Developer/Shared/Xcode/Plug-ins/Alcatraz.xcplugin

2. 找到这个UUID，copy一下

defaults read /Applications/Xcode.app/Contents/Info DVTPlugInCompatibilityUUID

3.添加这个UUID，（把你copy的替换add后面的UUID）

find ~/Library/Application\ Support/Developer/Shared/Xcode/Plug-ins -name Info.plist -maxdepth 3 | xargs -I{} defaults write {} DVTPlugInCompatibilityUUIDs -array-add E0A62D1F-3C18-4D74-BFE5-A4166D643966
