No. Every where you can provide an instance, you should be able to provide a Class to. For example, it's perfectly legal to register a Class as a notification observer (and use a Class method as target). It also perfectly legal to register a Class as a delegate and implements Class method instead of instance methods to handle message.

An Class method is just an instance method of the Class Object.

Class methods are prefixed with a +, and I don't think
there ever was a documented +encodeWithCoder: method
of NSObject or any other class, so it looks like it
was simply a quirk of the runtime that this ever
worked at all.

I am not able to think of a reason for this

the new dynamic nature of Classes prevents my

Is this a genuine regression or should I have never
