what you say wrapper function do you mean the ref counting functions when you pass around the interface?

I guess for ref counting you're supposed to cast the class to the interface (which is an expensive runtime lookup) and then pass that thing around? That seems like a crazy way to get ref counting plus you need to cast the interface back to the class if you want to call other methods? I still don't get this pattern. ARC should be handled by the compiler and be on the class itself, not some additional object you need to create and then store.
