Smart pointers instead of GC?

Oh, no. Beware of closures. That's a frequent problem in Objective-C 
ARC, even for those who understand ARC well. You have to be very 
careful of closures creating cycles if you use them as callbacks. For 
instance, you have a view that has a pointer to the model and sets a 
callback for the model to call when something change to update the 
view; that's a cycle and you need to use a weak ref to the view within 
the closure. Pretty common pattern.
