Well, it's very similar to Scala's pattern matching. Not as elegant as Erlang or Haskell's. Objective-C, which is what Swift is being compared to here, doesn't have pattern matching. An attempt to write something similar in Objective-C would be much more verbose, unsafe and almost certainly uglier.
