Null pointer dereferences do crash in Objective-C. Sending messages to nil is generally not nonsense in Objective-C, though. It has well-defined semantics and is useful in many cases. It isn't a "Don't crash when faced with nonsense" policy. I'm not sure the benefits are enough to justify its propensity to trip people up, but it's not like it's just some kind of crash prevention.
