In case you were wondering who was going to give it to you…

dmx.swift

import Swift

struct Giver {
    enum Receiver {
        case ya
    }
    
    private var name: String
    
    init(name: String) {
        self.name = name
    }
    
    func gonnaGiveIt(to: Receiver) {
        print("\(name) intends to give it to \(to).")
    }
}

let X = Giver(name: "X")
X.gonnaGiveIt(to: .ya)
