ios – UIButton’s addTarget not working in Swift

I am engaged on an iOS app in Swift, and I’ve encountered a difficulty with a UIButton’s addTarget not working as anticipated. I’ve tried to arrange a button to set off an motion, however for some motive, it is not responding to faucets. I’ve supplied my code beneath for reference.

class ErrorMessageView: UIView {
    let tryButton = UIButton()

    non-public lazy var buttonView: UIView = {
        let view = UIView()
        view.translatesAutoresizingMaskIntoConstraints = false
        return view
    }()

    non-public func configureTryButton() {
        tryButton.setTitle("Strive Once more", for: .regular)
        tryButton.addTarget(self, motion: #selector(self.buttonTapped), for: .touchUpInside)
        tryButton.translatesAutoresizingMaskIntoConstraints = false
    }

    var buttonTapHandler: (() -> Void)?

    init() {
        tremendous.init(body: .zero)
        configureTryButton()
        setupUI()
    }

    non-public func setupUI() {
        buttonView.addSubview(tryButton)
        addSubview(mainStackView)
    }

    @objc non-public func buttonTapped() {
        buttonTapHandler?()
    }
}

extension UIViewController {
    func showErrorMessageWithTryButton(tapHandler: @escaping () -> ()) {
        DispatchQueue.major.async {
            let errorView = self.setupErrorMessageWithButton(tapHandler: tapHandler)
            self.view.addSubview(errorView)
        }
    }

    non-public func setupErrorMessageWithButton(tapHandler: @escaping () -> ()) -> UIView {
        let loadingView = UIView(body: .zero)
        DispatchQueue.major.async {
            let errorView = ErrorMessageView()
            loadingView.addSubview(errorView)
            errorView.buttonTapHandler = tapHandler
            errorView.translatesAutoresizingMaskIntoConstraints = false
            NSLayoutConstraint.activate([
                errorView.centerXAnchor.constraint(equalTo: self.view.centerXAnchor),
                errorView.centerYAnchor.constraint(equalTo: self.view.centerYAnchor),
                errorView.leadingAnchor.constraint(equalTo: self.view.leadingAnchor, constant: 20),
                errorView.trailingAnchor.constraint(equalTo: self.view.trailingAnchor, constant: -20),
            ])
        }
    }
}

class ViewController: UIViewController {
    override func viewDidLoad() {
        tremendous.viewDidLoad()
        self.showErrorMessageWithTryButton {
            self.reloadPage()
        }
    }

    func reloadPage() {
        print("Reload Web page")
    }
}

I’ve adopted the usual setup for including a goal motion to a UIButton, however it’s nonetheless not working. Tapping the button does not set off the buttonTapped operate. I am making an attempt to name the reloadPage operate in my ViewController when the button is tapped, however it’s not occurring.

Thanks upfront in your assist!
