It also means that every third party API provider will *never* be able to change any method signature from failable to non-failable or vice-versa. That is a really bad thing! This concern is why Microsoft rightly chose to have *only* non-checked exceptions in C# (Java has both checked and non-checked). _______________________________________________ swift-users mailing list swift-users@swift.org https://lists.swift.org/mailman/listinfo/swift-users
