iOS Swift 2.0 Enumerations and Optionals Objects and Optionals Enums with Raw Values

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!
