Support for automatic garbage collection. The gcc man page that comes with Xcode 2.2+ has a description of how this feature can be enabled and how it basically works.

I don't really get this interest in garbage collection... the autorelease pools take care of temporary variables, and accessors take care of the longer term. Is GC being thrown in as a sop for the buzzword programmers? ("Oh my God, I can't program without polymorphic multiple inheritance abstract virtual base classes!")

The improvement for automatically creating accessor methods (via method attributes?) looks good, though I'm still a little leery about Key Value Coding violating encapsulation, and that trend seems to be accelerating with Core Data's objects not having prefixes in the global namespace.

Eg, this is something that bothers me... using GDB on some random view object reveals instance variables with names like:

_frame, _bounds, _window, _gState, _frameMatrix, _drawMatrix, _dragTypes, _vFlags

What if this object were KVC compliant, or a Core Data object, and I retrieved a variable that matched one of the above names? What if my Core Data object had a variable conflicting with one of the above names?

One of the improvements I'd like to see is for Apple to put a prefix on its instance variables so that they do NOT reserve that _naming for themselves!
