Answer 1

In swift 4.0

Create a delegate on class that need to send some data or provide some functionality to other classes

Like

protocol GetGameStatus {
    var score: score { get }
    func getPlayerDetails()
}

After that in the class that going to confirm to this delegate

class SnakesAndLadders: GetGameStatus {
    func getPlayerDetails() {

 }
}
