I'm not really sure why this code doesn't get accepted, can someone help me see what is wrong with it?

I created a constant direction of type Compass and assigned it the value found in the enum's case of South. I am really confused about the whole enum initialisers thing.

I would greatly appreciate any help.

enums.swift 
enum Compass: Int {
    case North = 1
    case South
    case East
    case West
}

let direction: Compass
if let dir = Compass(rawValue: 2) {
    direction = dir
}

Nikita, you had the right idea. You just did more work than is needed:

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

let direction = Compass(rawValue: 2)

happy coding!
