Could you elaborate?  If I subclass NSView and add an ivar named

Yes, but not a runtime error, and it wouldn't break binary compatibility. So it wouldn't affect users, only you (or other people using your source code), and it's easy to fix with a quick Refactor command.

Unlike a method-name conflict, which _would_ break existing binary copies of your app, in strange and hard-to-predict ways.
