| /* | ||
| As part of fully implementing (SE–0054), ImplicitlyUnwrappedOptional<T> is now an unavailable typealias of Optional<T>. Declarations annotated with ‘!’ have the type Optional<T>. If an expression involving one of these values will not compile successfully with the type Optional<T>, it is implicitly unwrapped, producing a value of type T. In some cases this will cause code that previously compiled to require updating. Please see this blog post for more information: (Reimplementation of Implicitly Unwrapped Optionals). (33272674) | ||
