Reference counting is a form of garbage collection.

I don't think so.
Garbage collectors do use reference counting, yes. But reference counting alone is not garbage collection.

With garbage collection you usually have a separate thread that's responsible for cleaning up the no longer used objects (those with a reference count of zero). This bears a specific problem: You won't know in advance exactly when an object will be freed (whenever the garbage collector finds it).

This is different in Objective-C. Objects are freed instantly when their reference count reaches zero.
