You don’t have permission to save the file “KeyBindings” in the folder “UserData”.

Ye. I read your source code and test the function of add KeyBinding, but got this problem. Any other step I should do so that I can modify KeyBindings file?

You can manually bind the keys from Xcode -> Preferences -> Key Bindings. The patching of KeyBindings file solution might not be supported on the newer versions of Xcode, I'd need to check that.
