Hi Joel,

Your enum is saying that each of these values are classes, but that's invalid in Swift. Here's the valid way of defining an enum.

enum Speed  {
   case slow
   case medium
   case fast
}

or for short

enum Speed {
   case slow, medium, fast
}

Hope I've helped. Happy Coding! :)

What weird syntax. In C, it's just enum Speed { Slow, Medium, Fast } You don't really need switch/case statements; after all the & and >> operators are your friends. :-)
