The “only available after importing Foundation” thing has been around since 1.0
— it’s an artifact of the bridging of String and NSString*. After importing
Foundation, the methods of NSString are implicitly available as an extension of
String. I would think that by now the Swift standard library would have added
those methods, but I guess not all of them…

* And IIRC it also manifests with Array, Dictionary, and other bridged classes.
