如何在Swift中检查Enum类型？

我正在编写一个序列化程序,可以序列化枚举和其他 Swift类型(字符串,对象等).所以我需要检查传递给我的序列化程序的Any参数是否是Enum或其他东西.似乎在Swift中执行此操作的唯一方法是使用反射.下面的代码是否合理或是否有更好的方法来检查枚举类型？

enum Things {
    case Thing1
    case Thing2
}

let something:Any = Things.Thing1
let mirror = Mirror(reflecting: something)
if (mirror.displayStyle == .Enum) {
    print("Reflected type is Enum") // works
}

解决方法

enum Things {
    case Thing1
    case Thing2
}

let something:Any = Things.Thing1

something.dynamicType == Things.self // true

根据讨论更新..

protocol P {}
enum Things:P {
    case Thing1
    case Thing2
}
enum Things2:P{
    case Things21
}

let something:Any = Things.Thing1
something.dynamicType == Things.self // true
if let p = something as? P {
    print(true)
}

let somethingelse: Any = Things2.Things21
if let p = somethingelse as? P {
    print(true)
}
