Is it possible to declare swift generic for enums of particular type?

Question

Would it be possible to have a function that allows any enum where the rawValue is of a certain type? For example, any enum that has a string rawValue.

Answer 1

This can be done using generics and the "where" keyword

enum EnumString: String {
    case A = "test"
}

func printEnum<T: RawRepresentable where T.RawValue == String>(arg: T) {
    print(arg.rawValue)
}
printEnum(EnumString.A) //Prints "test"
