What does the 'UN' stand for in UNNotification?

I noticed over the years that Apple has dropped prefixes such as 'NS' when using Swift. Now as I'm going through a local notifications tutorial, I see that UIUserNotificationSettings has been deprecated and it asks that we use UNNotificationSettings instead. I understand that 'NS' stood for Next Step so is there a correlation possibly that 'UN' stands for something?

As a general rule every item inside a framework takes it's name prefix 

UIButton -> UIKit -> User Interface

AVAudioPlayer -> AVFoundation -> Audio Video

UNNotification -> UserNotifications - > User Notification

Classes such as UNNotificationSettings and other UNNotification... classes are in the UserNotifications framework. So it seems the "UN" is for User Notifications.
