"No doubt straight up ARC with refcounting bumps on every function call,etc..."

Yeah, but in Swift you don't do that. From what I'm told, the compiler's static analysis has gotten a lot smarter in determining when a ref-count bump is needed, and the increased use of struct-based value types in the language leads more and more to situations where a refcount bump isn't needed at all since there's no object reference in the first place.
