Hi :-)

You don't need to use if let to declare a constant. Furthermore, the challenge has an error: you can only pass by naming the constant "direction" without capital D...

enum Compass: Int {
     case North = 1
     case South = 2
     case East = 3
     case West = 4
}
let direction = Compass(rawValue: 2)
