UIButton inside UIView inside UIScrollView not firing tap action

Question

I've been looking for this for hours and have no luck yet. I want to use two custom views inside a scrollview. The first view have a button as a subview that leads the user to the next page(scrolls down). But the button action it's never fired. If I use the button as a scrollview subview everything works fine, but that's not what I want.

The code for the scrollview view controller:

    class ViewController: UIViewController {

    @IBOutlet weak var scrollView: UIScrollView!

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

    override func viewDidLayoutSubviews() {
        super.viewDidLayoutSubviews()
        let redView = View1()
        redView.view.frame = CGRect(x: 0, y: 0, width: self.view.frame.width, height: self.scrollView.frame.height)
        self.scrollView.addSubview(redView.view!)

        let blueView = UIView(frame: CGRect(x: 0, y: self.scrollView.frame.height, width: self.view.frame.width, height: self.scrollView.frame.height))
        blueView.backgroundColor = .blue
        self.scrollView.addSubview(blueView)

        self.scrollView.contentSize = CGSize(width: self.view.frame.width, height: self.scrollView.frame.height * 2)
    }

    func go(to page: Int) {
        let y = CGFloat(page) * self.scrollView.frame.size.height
        self.scrollView.setContentOffset(CGPoint(x: 0, y: y), animated: true)
    }
}

ScrollView Storyboard Configuration

The code of the View1 Class:

    class View1: UIViewController {

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

    @IBAction func didTouchUpInsideMoreInfoButton(_ sender: Any) {
        print("test")
    }
}

Any ideas are welcome. Thanks in advance.

Turn out that I was using a view controller's view and for some reason, the selectors don't work this way. So, what I did was to create a UIView only and then everything works just fine.
