@mpweiher Which dynamic features were removed from Objective-C?
Marcel Weiher ‏@mpweiher May 21

@mjtsai It’s a direction. Static checking has been tightened at every turn, including turning what used to be warnings into errors.

@mjtsai With ARC, performSelector: and variants are very hard to get right…and ARC in general wants to know types statically.
