Doesn't show up in extensions on macOS Catalina

[melgu]

The sudo /usr/libexec/xpccachectl command returns command not found.

Same problem. But found answer here: https://stackoverflow.com/questions/47690605/script-xpccachectl-not-found

I don't think you need to run xpccachectl at all; it isn't needed since El Capitan. @Xopoko did you verify that this extension works on the macOS Catalina beta?

[Xopoko]

Yes, i confirm.

Is it working at Xcode 11.3.1? I followed all the process in README.me but I can't see anything in Editor pane.
