Application Delegate Objects changed?

[ncc1701e]

One of the changes Im noticing in Xcode 4.2 is that in the "Single View" and the "Empty Application" iOS application templates, the app delegate no longer seems to subclass NSObject. It seems to subclass UIResponder. Is this correct or am I just picking the wrong templates (for iOS view based apps) being a newbie?

I'm seeing the same UIResponder class as the default superclass for the AppDelegate. The AppDelegate is also called just AppDelegate and doesn't have the project name prefixed. I think that's just some of the changes.

I have further noticed that UIResponder subclasses NSObject anyway so in a way the appdelegate is still subclassing NSObject thru the inheritance chain:

AppDelegate : UIResponder : NSObject

The changes are taking some getting used to but they all seem to make developing easier especially story board and ARC.
