The script and the commands provided herein is used at your own risk. Un-signing Xcode is dangerous and could leave Xcode vulnerable, only use this script if you understand the risks. The author of this script is waiving all liability.
Please also note this script has been untested and just put here as a pointer on how to un-sign Xcode 8+ to allow 3rd party plug-ins like Alcatraz.io.
Might be better to just type the commands above instead of running the script as I've not actually tried the script yet, just executed similar commands manually and then wrote the script after.
Note, it does not modify the original Xcode.app bundle and instead copies it so the original will still receive updates etc. You can switch between signed and unsigned Xcodes at your will.
Hopefully this script will be unneeded once Apple add deeper extension support to Xcode in the future. For now only
