Please Help

I can not figure out how to solve this issue

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

Hey there Mehran,

It looks like the code complies when you use the lowercase for all of the case statements. I literally copy and pasted your code and then lowercased the case statements with a successful compile. 

enum Compass: Int {
     case north = 1
     case south = 2
     case east = 3
     case west = 4
}
let direction = Compass(rawValue: 2)

The Treehouse compiler can be VERY picky.

Hope this helps!
