Enum rawValue code does not pass

I need some help figuring out why this code does not pass.

enums.swift 
enum Compass {
    case north = 1
  case south = 2
  case east = 3
  case west = 4
}

let direction = Compass.south(rawValue: 2)

I get this error: "Bummer: Make sure you're creating an enum value using the raw value initializer and assigning the result to direction"

The enum needs to be assigned a raw value type of Int

enum Compass: Int {
// cases are fine
}

Also

Compass.south doesn't have an initializer, you need to call it on Compass:

let direction = Compass(rawValue: 2)
