Swiftのenum(列挙)の宣言

Swift

enum Fruits { case Apple case Banana case Orange }

1 2 3 4 5

enum Fruits {   case Apple   case Banana   case Orange }

or

Swift

enum Fruits {Apple, Banana, Orange}

1	enum Fruits {Apple, Banana, Orange}

 

宣言時に値を代入する場合は

Swift

enum Fruits: String { case Apple = "りんご" case Banana = "ばなな" case Orange = "おれんじ" }

1 2 3 4 5

enum Fruits: String {   case Apple = "りんご"   case Banana = "ばなな"   case Orange = "おれんじ" }

 

 

Swiftのenumの呼び出し

Swift

var fruit = Fruits.Banana

1	var fruit = Fruits.Banana

or

Swift

var fruit: Fruits = .Banana

1	var fruit: Fruits = .Banana

 

値を呼び出し(rawValue)

Swift

print(fruit.rawValue)

1	print(fruit.rawValue)
