I typed this into a playground: > class SBase { > func a () { > if self is SArray { print ("SArray") } else { print ("not > SArray") } > } > } > > class SArray: SBase { > } > > let s1 = SBase () > s1.a () > let s2 = SArray () > s2.a () and got this output: > not SArray > SArray So you’re doing something different. Can you show a code fragment that demonstrates the problem in a playground? (I am using Swift 3, but this behavior should be the same in Swift 2.) _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
