Name of enumeration value in Swift, does not return String. :( description)

someone already said that to print a name out of an enum you have to implement something like this:

enum itemlist: Int { case nothing = 0, healingpotion, manapotion

var description : String {
    get {
        switch(self) {
        case .nothing:
            return "---"
        case .healingpotion:
            return "Healingpotion"
        case .manapotion:
            return "Manapotion"
        }
    }
}

}

when i call this parameter it stil returns the number. what am i missing?

player.item1.description // result 1 and not healingpotion
