According to Dave Mark in "Beginning iPhone Development: Exploring the iPhone SDK
":"If you are coming to iPhone with previous Cocoa experience, a few tools that you're probably accustomed to using aren't available on the iPhone. The iPhone SDK doesn't support Core Data or Cocoa Bindings. We mentioned earlier that Cocoa Touch uses Objective C 2.0, but one of the key new features of that language is not available on iPhone: Cocoa Touch does not support garbage collection."
Its a good thing I spent a lot of time reviewing memory management. It looks like those retain and release statements will come in handy. I'm also glad I stopped at Chapter 8 in "Cocoa(R) Programming for Mac(R) OS X (3rd Edition)" and picked up this new book. Core Data was only a few chapters away and I would have wasted lots of precious time learning something I wouldn't be able to use.
