enum GameState {
    case NotStarted
    case InPlay
    case GameWon
    case PlayingForHigherScores
    case GameLost
    
    func simpleDescription(state: GameState) -> String {
        switch state {
        case .NotStarted:
            return "NotStarted"
        case .InPlay:
            return "InPlay"
        case .GameWon:
            return "GameWon"
        case .PlayingForHigherScores:
            return "PlayingForHigherScores"
        case .GameLost:
            return "GameLost"
        }
    }
    
    func description() -> String {
        return self.simpleDescription(self)
    }
}


// Xcode 7 beta 3 updated Swift 2.0 and it copies name of a case to its raw value.
// It should look like this:

enum GameState: String {
    case NotStarted // rawValue = "NotStarted", the same with other cases
    case InPlay
    case GameWon
    case PlayingForHigherScores
    case GameLost
}
