I myself would already be happy if Swift had an equivalent to NS_REQUIRES_SUPER (preferably with a different name ;-).
The ability to indicate that super shouldn't be called when overriding would be nice as well — both situations happen in Cocoa, and it isn't enforced, but only documented.
I don't have any examples where the position of the call to super matters, and my personal opinion is that this feature wouldn't pay off:
Of course, there are situations where order is important — but as with willSet/didSet, it might only be important for the overriding class, not for super.
