I'm sure the problem isn't caused by this but here my custom tableview cell whole code: class customCell: UITableViewCell {               let testdetails = testdetail()          var count = 0           let cellView: UIView = {                let view = UIView()                view.backgroundColor = .white                return view            }()                        let imageOrderForCell: UIImageView = {                let iv = UIImageView()                iv.contentMode = .scaleAspectFit                iv.image = UIImage(named: "checked")                return iv            }()                        let sepetLabel: UILabel = {                let label = UILabel()                label.text = "sepetteki ürün"                label.textColor = .darkGray                label.font = UIFont(name:"Comfortaa-Bold", size: 15)                label.translatesAutoresizingMaskIntoConstraints = false                return label            }()                        let countBasketLabel: UILabel = {                let countLabel = UILabel()                countLabel.text = "x0"                countLabel.textColor = .orange                countLabel.font = UIFont(name:"Comfortaa-Bold", size: 15)                countLabel.translatesAutoresizingMaskIntoConstraints = false                return countLabel            }()                        let priceBasketLabel: UILabel = {                let pricelabel = UILabel()                pricelabel.textColor = .black                pricelabel.font = UIFont(name:"Comfortaa-Bold", size: 15)                return pricelabel            }()                        let deleteButton: UIButton = {                let button = UIButton(type: .system)                button.setImage(UIImage(named: "delete"), for: .normal)                button.tintColor = .black                button.layer.cornerRadius = 5                button.addTarget(self, action: #selector(testdetail.deleteAction(sender:)), for: .touchUpInside)                return button            }()            lazy var addButton: UIButton = {                let button = UIButton(type: .system)                button.setImage(UIImage(named: "add"), for: .normal)                button.tintColor = .black                button.layer.cornerRadius = 5                return button            }()                        override init(style: UITableViewCell.CellStyle, reuseIdentifier: String?) {                super.init(style: style, reuseIdentifier: reuseIdentifier)                setup()            }                        required init?(coder aDecoder: NSCoder) {                fatalError("init(coder:) has not been implemented")            }                                    func setup() {                backgroundColor = .clear                addSubview(cellView)                cellView.addSubview(sepetLabel)                cellView.addSubview(priceBasketLabel)                cellView.addSubview(countBasketLabel)                cellView.addSubview(addButton)                cellView.addSubview(deleteButton)                                cellView.anchor(top: topAnchor, left: leftAnchor, bottom: bottomAnchor, right: rightAnchor, paddingTop: 4, paddingLeft: 8, paddingBottom: 4, paddingRight: 8, width: 40, height: 40)                                sepetLabel.anchor(top: nil, left: cellView.leftAnchor, bottom: nil, right: rightAnchor, paddingTop: 0, paddingLeft: 6, paddingBottom: 0, paddingRight: 0, width: 25, height: 25)                sepetLabel.centerYAnchor.constraint(equalTo: cellView.centerYAnchor).isActive = true                                                priceBasketLabel.anchor(top: nil, left: nil, bottom: nil, right: deleteButton.leftAnchor, paddingTop: 0, paddingLeft: 10, paddingBottom: 0, paddingRight: 20, width: 0, height: 35)                priceBasketLabel.centerYAnchor.constraint(equalTo: sepetLabel.centerYAnchor).isActive = true                                                countBasketLabel.anchor(top: nil, left: nil, bottom: nil, right: addButton.leftAnchor, paddingTop: 0, paddingLeft: 1, paddingBottom: 0, paddingRight: 1, width: 30, height: 25)                countBasketLabel.centerYAnchor.constraint(equalTo: sepetLabel.centerYAnchor).isActive = true                                                     addButton.anchor(top: nil, left: nil, bottom: nil, right: rightAnchor, paddingTop: 0, paddingLeft: 2, paddingBottom: 0, paddingRight: 8, width: 30, height: 30)                addButton.centerYAnchor.constraint(equalTo: sepetLabel.centerYAnchor).isActive = true                                deleteButton.anchor(top: nil, left: nil, bottom: nil, right: countBasketLabel.leftAnchor, paddingTop: 0, paddingLeft: 2, paddingBottom: 0, paddingRight: 8, width: 30, height: 30)                deleteButton.centerYAnchor.constraint(equalTo: sepetLabel.centerYAnchor).isActive = true            } }

I replaced that because I try to solve it but in original version is my first post. The problem continues. Also I have class header of course.

addButton on the custom tableview cell. It is all working before the update Xcode. Add functions on same class but in custom cell view have button's properties.
