升級到Xcode6使用不了以前的插件（VVDocumenter、KSImageNamed、Alcatraz）解決：

1)到Xcode安裝插件的路徑下: library/Application Support/Developer/Shared/Xcode/Plug-ins
2)右鍵點(diǎn)擊插件，查看包內(nèi)容，打開info.plist 文件，找到DVTPlugInCompatibilityUUIDs，點(diǎn)擊+號添加： C4A681B0-4A26-480E-93EC-1218098B9AA0
3)保存文件，重啟Xcode

No Need to repeat for all plugins that are already installed to Xcode 6.

或者使用命令行：find ~/Library/Application\ Support/Developer/Shared/Xcode/Plug-ins -name Info.plist -maxdepth 3 | xargs -I{} defaults write {} DVTPlugInCompatibilityUUIDs -array-add defaults read /Applications/Xcode.app/Contents/Info.plist DVTPlugInCompatibilityUUID

Xcode7

升級到Xcode7后又用不了了，上面的步驟也不管用，原因是是新的xCode的UUID沒有在插件的配置文件中注冊進(jìn)去。在網(wǎng)上找了一位大神的使用命令行的解決方案，記錄如下：

1. 得到Xcode的UUID：

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

2. 循環(huán)插入UUID:
   find ~/Library/Application\ Support/Developer/Shared/Xcode/Plug-ins/ -name Info.plist -maxdepth 3| xargs -I{} defaults write {} DVTPlugInCompatibilityUUIDs -array-add '0420B86A-AA43-4792-9ED0-6FE0F2B16A13'

3. 重啟Xcode，會跳出一個彈框，選擇loadBoundle就·
