No. That would be much too slow.
Some classes in Cocoa use them, but nothing in ObjC itself.
Pregunta
Does anything in Objective-C use associative references under the hood? For example, do property setter and getter use it behind the scene?

I would think associative references would be used explicitly by developers extending exiting classes. When the compiler generates getters and setters it has access to the source code.
