update_xcode_plugins
This tool adds the missing UUIDs into the installed Xcode plugins so that they can be loaded by newer versions of Xcode.
You can choose to run it once or install a launch agent that will trigger the tool every time any of your installed plugins are modified or Xcode/Xcode-beta gets updated.
This tool also allows you to unsign Xcode in order to run plugins on Xcode 8 and later. For more information on why this is needed, see alcatraz/Alcatraz#475.
When unsigning Xcode, you will also be prompted to unsign xcodebuild; Doing so will allow xcodebuild to load plugins and silence the library validation warnings. More info at #8.
If you are having any issues, please check common issues before creating an issue.
