These are excellent points, Brent. Many, many Apple Objective-C APIs have not yet been audited for nullability, and IUOs remain a useful tool until they are — that’s the main reason we’re not proposing getting rid of them entirely. I hadn’t considered Linux but that’s a compelling argument as well. — Chris W. _______________________________________________ swift-evolution mailing list [email protected] https://lists.swift.org/mailman/listinfo/swift-evolution
