I am having problem with code challenge where it says I need to use the enum initializer. What do I do differently?

Thank you in advanced for all your help

enum Compass: Int {

case North = 1

case East = 2

case South = 3

case West = 4 }

let direction = Compass.West.rawValue'''

The rawValue initializer can initialize an enum case using its raw value, in this case an integer. Try this:

enum Compass: Int {
  case North = 1
  case East = 2
  case South = 3
  case West = 4
}

let direction = Compass(rawValue: 4) \\ returns Compass.West
