Errors:

*** Terminating app due to uncaught exception 'NSGenericException', reason: 'Unable to activate constraint with anchors <NSLayoutXAxisAnchor:0x600001575e00 "UIButton:0x7fafea124c50.centerX"> and <NSLayoutXAxisAnchor:0x600001570980 "UIView:0x7fafdffa97f0.centerX"> because they have no common ancestor.  Does the constraint or its anchors reference items in different view hierarchies?  That's illegal.'

UIView Events

If you're embeding UIstackView in a UIView class and are not able to get some event responses, you need disable its user interaction flag.

class CustomView: UIButton {
	init() {
        super.init(frame: .zero)
		labelStackView.addArrangedSubviews(titleStackView, descriptionLabel)
        addSubview(labelStackView)
    }
    
	private(set) var labelStackView: UIStackView = {
		stackView.isUserInteractionEnabled = false
	}
