Do I get it right: I don't subclass UIApplication to access didFinishLaunching, I simply use one of it's methods?

This follows giving the wrong answer on one of quiz questions and not understanding the logic behind the right answer.

The AppDelegate.swift conforms to the protocol UIApplicationDelegate. Therefore didFinishLaunching should be called from within here.
