I believe that, in this example, `y` is of type `Int?`, that is, a non-autounwrapped optional. An autounwrapped optional is only unwrapped if Swift cannot make the code type-check without unwrapping it. -- Brent Royal-Gordon Architechies _______________________________________________ swift-evolution mailing list swift-evolution@swift.org https://lists.swift.org/mailman/listinfo/swift-evolution
