Stuck on a challenging question from Enums with Raw Values code challenge

Let's get in some practice creating enums with raw values. Declare an enum named Compass with a raw value of type Int.

Give the enum 4 members: north, south, east and west and assign them default raw values.

Assign the enum value Compass.south to a constant named direction, by using a raw value with Compass' initializer method.

My code:

 enum Compass: Int {

    case north = 1
    case south
    case east
    case west

}

let direction = Compass.south.rawValue

It didn't pass the code challenge, must be a bug?

let direction = Compass(rawValue: 2)

The challenge is to create a instance of Compass.south enum using rawValue, your code will get the raw value of the Compass.south which is 2.
