Why isn AppKit compiled using ARC? Probably because it has a track record as it is and would likely gain nothing in a functional sense.
ARC works as advertised in general usage but managing unsafe_unretained references is as delicate a business as it is when using manual ref counting. These sorts of difficulties are the inspiration of course for managed languages like C# which are largely free from these niceties. However Obj-C’s dalliance with GC didn’t work out too well and there were as many issues with -finalise as there are with -dealloc.
