Ok, this statement isn’t factually true: I’ll admit that there are two related things to this: the GNU ObjC runtime does track some method types, and ObjC does have @encode strings, which encode a subset of the ObjC type system. While both are true, neither are used by Swift AnyObject lookup, so the rest of the points still hold. -Chris _______________________________________________ swift-evolution mailing list swift-evolution@swift.org https://lists.swift.org/mailman/listinfo/swift-evolution
