Query Apple's FindMy network with Python

It's not clear to me how to actually get the required plist file to make this library work. Neither of the scripts in this issue seem to work: https://github.com/malmeloo/FindMy.py/issues/31

Is the syntax to run them just `swift <filename.swift>`?

Swift/ErrorType.swift:253: Fatal error: Error raised at top level: main.MyError.noPassword

Which version of MacOS are you using? I believe Apple has made changes to the keychain in the latest version which prevents the scripts from working properly.

The only Apple "device" I have regular access to is a hackintosh, so this stuff is frustratingly hard to debug. So far I've been relying on efforts from the community, but the scripts appear to be somewhat flaky and don't always work for everyone unfortunately.
