I've two things to say:

1) There is 'pyobjc-framework-CoreLocation' that wraps the CoreLocation APIs. Using objc.loadBunlde works as well, but the CoreLocation wrapper makes the constants in the framework available and is more convenient to use ('import CoreLocation').

2) You don't use an eventloop, which is probably why your callback doesn't get called.
