enum Count : Int{ case begin = 1 case Two,Three, Four } let new = Count.begin let newValue = new.rawValue // = 1 let a = Count.Three let b = a.rawValue // 3 enum Rank: Int { case Ace = 1 case Two, Three, Four, Five, Six, Seven, Eight, Nine, Ten case Jack, Queen, King func simpleDescription() -> String { switch self { case .Ace: return "ace" case .Jack: return "jack" case .Queen: return "queen" case .King: return "king" default: return String(self.rawValue) } } } let ace = Rank.Ace let aceRawValue = ace.rawValue let a = Rank.Eight let b = Rank.Three let c = Rank.Ace let d = a.rawValue //8 let e = b.rawValue //3 let f = Rank.Jack let g = f.simpleDescription() // "Jack" |
