1.枚举语法：
enum Platform{@H_403_6@ case Windows@H_403_6@ case Linux@H_403_6@ case MacOs@H_403_6@ }@H_403_6@ var myPlatform = platform.windows@H_403_6@ myPlatform= .Linux@H_403_6@ switch myPlatform{@H_403_6@ case .Windows:@H_403_6@ println(“这是Windows平台”)@H_403_6@ default:@H_403_6@ println("不支持该平台”)@H_403_6@ }
2.关联值
enum Password{@H_403_6@ case DigitPassword(Int)@H_403_6@ case StringPassword(String)@H_403_6@ }@H_403_6@ var password = Password.DigitPassword(4078385)@H_403_6@ password = Password.StringPassword(“admin”)@H_403_6@ switch password{@H_403_6@ case .DigitPassword(let digitPwd):@H_403_6@ println(“数字密码是：\(digitPwd)”)@H_403_6@ case .StringPassword(let strPwd)@H_403_6@ println(“字符密码是：\(strPwd)”)@H_403_6@ }3.原始值
enum ASCIIControlCharacter:Character{@H_403_6@ case Tab = “\t"@H_403_6@ case LineFeed = “\n"@H_403_6@ case CarriageReturn = “\t"@H_403_6@ }4.示例代码：
enum CompassPoint{
case North
case South
case East
case West
}
var dir = CompassPoint.East
dir = .West
switch dir{
case .North:
print("North")
default:
print("Other")
