Как добавить событие касания программно к моему объекту UIView?

Question

Я программно создаю объект в своей раскадровке. Я хочу иметь приложение Dynami c, которое может добавлять и удалять карты (объекты класса PlayingCardView) в режиме реального времени. Мне нужно иметь возможность прикоснуться к этим картам.

Кто-нибудь знает, как добавить событие касания к этому объекту? В viewcontroller у вас есть метод, который я использовал, но он не работает.

import UIKit

class ViewController: UIViewController {


    var game = Concentration()

    var gesture: UITapGestureRecognizer { let t = UITapGestureRecognizer(target: self, action:  #selector(someAction(_:)))
        return t
    }

    override func viewDidLoad() {
        super.viewDidLoad()
    }

    @IBAction func CreateGame(_ sender: UIButton) {
        newGame()
    }

    func newGame() {
        game.height = heightView
        game.width = widthView
        game.addCards()

        view.addSubview(game.cards[1])
        game.cards[1].addGestureRecognizer(gesture)
        print("New Game started")
    }
    @objc func someAction(_ sender:UITapGestureRecognizer){
        if sender.state == .ended
        {
        print("Choose")
        }
    }

    func displayCards (){


    }


}

extension ViewController{

    private var widthView: CGFloat {
        return view.bounds.size.width}
    private var heightView: CGFloat {
        return view.bounds.size.height}

}

И есть класс, который я использую в качестве карты.

import UIKit
@IBDesignable

class PlayingCardView: UIView {



    var identifier:Int = 0
    var sign:Int = 1 {didSet{updateView()}}
    var color: UIColor = #colorLiteral(red: 0.4666666687, green: 0.7647058964, blue: 0.2666666806, alpha: 1) {didSet{updateView()}}
    var rank: Int = 3 {didSet{updateView()}}
    private static var identifierFactory = 0

    override init(frame: CGRect) {
        super.init(frame: frame)
        commonInit()
    }

    required init?(coder: NSCoder) {
        super.init(coder: coder)
        commonInit()
    }
    private static func getUniqueIdentifier () -> Int {
        PlayingCardView.identifierFactory += 1
        return identifierFactory
    }

    func commonInit()
    {
        identifier = PlayingCardView.getUniqueIdentifier()
    }


    override func draw(_ rect: CGRect) {

        let roundedRect = UIBezierPath(roundedRect: bounds, cornerRadius: cornerSize)
        UIColor.white.setFill()
        roundedRect.fill()

        let shape = oval(howMany: rank)
        UIColor.red.setStroke()
        shape.lineWidth = 3.0
        shape.stroke()

    }

    private func oval (howMany: Int) ->UIBezierPath{

        let oval = UIBezierPath()

        switch howMany {
        case 1:
                oval.move(to: CGPoint(x: bounds.size.width/5, y: bounds.size.height*(1/2)))
            oval.addLine(to: CGPoint(x: oval.currentPoint.x+(bounds.size.width*(3/10)), y: oval.currentPoint.y+(bounds.size.height/10)))

            oval.close()
        case 3:

            oval.move(to: CGPoint(x: bounds.size.width/5, y: bounds.size.height*(1/5)))
            oval.addLine(to: CGPoint(x: oval.currentPoint.x+(bounds.size.width*(3/10)), y: oval.currentPoint.y+(bounds.size.height/10)))
