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

I'm gonna North again I guess

the error: Make sure you're creating an enum value using the raw value initializer and assigning the result to direction

enums.swift
enum Compass: Int {
case North = 0
case South = 180
case East = 90
case West = 270
}
let direction = Compass.South.rawValue

Hi, raw value initializer means that you grab an enum case by its raw value. What you've done is getting the raw value of Compass.south. :) The rawValue initializer looks like the following:

let direction = Compass(rawValue: 180)

thks again mate! any news from the previous code? cheers
