I do not understand why my enum initializer isn't working?

In this challenge, I did what Pasan did and it worked on Xcode too. I do not understand what is wrong with my code.

enums.swift 
enum Compass: Int {
  case north = 1
  case south = 2
  case east = 3
  case west = 4
}
 let value = 2
 if let direction = Compass(rawValue: value){
 print(direction)
 }

There's no need to use if let as you know you can initialise the enum with a raw value of 2 and you're not using direction afterwards. So, you can simplify your code to:

let direction = Compass(rawValue: 2)
