I haven't thought very hard about it, but I don't see why even C/C++ code can't be made to work in a GC environment, even older code that calls malloc/new/free/delete.
It can work, but it still requires a conservative collector, which brings in some compromise in efficiency.
Now I don't really know how much compromise in real-life apps, nor how much of a role this played in Apple's decision--it's just one example possibility. Also, remember, (from what I've seen) iOS performs better than Android on similar hardware--so it's not like there's a counter example of GC working really well for mobile.

Hey, feel free, I don't have anything else to say about it ;-) Well, OK, one thing, just to be clear--I'm as disappointed as anybody about GC being deprecated. I've long looked forward to it as the future, and was hopeful about seeing it move into iOS 5 or 6.
