Objective-C uses autorelease pools so deallocation doesn't happen immediately when the refcount goes to zero. Its reference counting implementation is smarter than a simple naïve one. Apple's GC implementation wasn't a Boehm GC [1]. It's true that it's hard to use a tracing GC with Objective-C, because of the C. But, if you want interoperability with C, you're kind of stuck.
