• Xcode 重签名证书：钥匙串访问—证书助理：创建证书 — 名称：XcodeResign 类型：代码签名签名：sudo codesign -f -s XcodeResign（证书名） /Applications/Xcode.app

签名问题
/Applications/Xcode.app: replacing existing signature
/Applications/Xcode.app: resource fork, Finder information, or similar detritus not allowed
解决命令：
sudo xattr -cr /Applications/Xcode.app

查看 Xcode 签名 UUID：defaults read /Applications/Xcode.app/Contents/Info DVTPlugInCompatibilityUUID
替换插件的 UUID：
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 DVTPlugInCompatibilityUUID

安装 Xvim2

cd XVim2
git checkout xcode10.1

defaults delete com.apple.dt.Xcode DVTPlugInManagerNonApplePlugIns-Xcode-x-x
完成后，重启 Xcode
