I agree that the IB implementation is crap. The API, on the other hand, is very nice. Although constraints can be slightly verbose, they are ages better than having to manually re-layout views after every single change of the superview's bounds. Spring and struts are nice, but cannot replace all of the CGGeometry math which is equally as, if not more, verbose than adding constraints. Autolayout is add-and-forget. The only downside is that it is iOS6+ only.
