Interesting Bits
PermissionController is a view controller subclass that appears on first run, informs the user about local notifications, and requests permission to display them. I built it using two design patterns central to Cocoa Touch: dependency injection and delegation. I gave PermissionController a type method, instantiate(with:), that returns a PermissionController with the provided delegate pre-injected.
The instance thus created contains very little custom code. All the “work” it does is directly related to controlling its view and subviews. Handling user interaction is delegated to the PermissionControllerDelegate.
