ARC is garbage collection, of course mighty Apple won't acknowledge that, because it doesn't suit their marketing, and they are to sell ARC after the Objective-C 2.0 conservative GC failure, given the underlying C semantics.
So they need to sell ARC as the great saviour, so much better than "GC".

Nope. Until they saw that (a) CocoaJava was a complete dud, not just technically, but also in terms of developers buy in and (b) Cocoa/ObjC was accepted well by a large part of the dev community.

In terms of the Apple ecosystem, "Garbage Collection" refers to the failed attempt to introduce a tracing garbage collector. Apple/OSX always had reference counting (introduced by NeXT pre-acquisition with Foundation in EOF and later in OPENSTEP 4.0), which technically is also a form of garbage collection, but again in this case the terms are distinct.

Again, in the Apple ecosystem, "Garbage Collection" always referred to the tracing collector, even before they had to abandon it due to it not working.
And ARC is markedly better than their GC, but only arguable and at best marginally better than the reference counting they had pre-GC, and in some significant sense worse. Which is why I generally don't use ARC. For my style of programming the benefits are minuscule and the drawbacks real.
