I want to make a truth or dare game in swift playground for iPad but I can't make a button that prints more than one dare or truth. I tried to make a var that have all dares and then i put it in the (class Responser NSObject )the var looks like this( var dares = ["dare1", "dare 2" ...]) but it is giving me error that says (cannot assign value of type '[String]'to type 'String') and the 2nd thing I tried was (let dares = ["dare 1", "dare 2"…]) that gave me the same error. my code looks like this import PlaygroundSupport import UIKit let View = UIView() View.backgroundColor = .blue let lbl = UILabel(frame: CGRect(x: 210, y: 329, width: 200, height: 50)) lbl.text = "hi!" View.addSubview(lbl) lbl.textColor = .white let button = UIButton(frame: CGRect(x: 67, y: 500, width: 100, height: 50)) button.backgroundColor = .green //button.setTitleColor(#colorLiteral(red: 0.0, green: 0.0, blue: 0.0, alpha: 1.0), for: UIControlState.selected) button.setTitle("button", for: UIControl.State.selected) button.layer.cornerRadius = 10 View.addSubview(button) let button1 = UIButton(frame: CGRect(x: 300, y: 500, width: 100, height: 50)) button1.backgroundColor = .red //button1.setTitleColor(#colorLiteral(red: 0.0, green: 0.0, blue: 0.0, alpha: 1.0), for: UIControlState.selected) button1.setTitle("button1", for: UIControl.State.selected) button1.layer.cornerRadius = 10 View.addSubview(button1) class Responser: NSObject {          //Method to be called     @objc func printname()     {         lbl.text = "1"     } } let responder = Responser() button.addTarget(responder, action: #selector(Responser.printname), for:.touchUpInside)   class Responser1: NSObject {          //Method to be called     @objc func printname()     {         lbl.text = "2"     } } let responder1 = Responser1() button1.addTarget(responder1, action: #selector(Responser1.printname), for:.touchUpInside) PlaygroundPage.current.liveView = View
