enum Suit: String {
    case spades = "?"
    case hearts = "?"
    case diamonds = "?"
    case clubs = "?"
}

例如,我该怎么做:

for suit in Suit {
    // do something with suit
    print(suit.rawValue)
}

结果示例:

?
?
?
?

鉴于以下枚举:

enum Audience {
    case Public
    case Friends
    case Private
}

如何"Public"从audience下面的常量中获取字符串？

let audience = Audience.Public
