How to create extension UITapGestureRecognizerDelegate or fix overlapping view SWIFT - ios

Question

I create this basic tap gesture function for dismissing view and I added a delegate to override tap when the user taps on another custom sheet (container).
#objc func handleTapGesture() {
dismiss(animated: true, completion: nil)
}
private func tapGestureToDissmis() {
let tap = UITapGestureRecognizer()
tap.addTarget(self, action: #selector(handleTapGesture))
tap.delegate = self
view.addGestureRecognizer(tap)
}
extension TextConfigurationVC : UIGestureRecognizerDelegate {
func gestureRecognizer(_ gestureRecognizer: UIGestureRecognizer, shouldReceive touch: UITouch) -> Bool {
if touch.view?.isDescendant(of: container) == true {
return false
}
return true
}
My problem is that I want to implement this for 8 screens and I don't want to repeat my self. i create in my UIViewcontroler extension file this tap function and I don't now how to pass this view :
extension UIViewController : UIGestureRecognizerDelegate {
public func gestureRecognizer(_ gestureRecognizer: UIGestureRecognizer, shouldReceive touch: UITouch) -> Bool {
if touch.view?.isDescendant(of: **<UIView>)** == true {
return false
}
return true
}
when I created the global container, each time it was called, it was overlapping each other
(tap x 6)

Simple way to handle individual tap action for views
extension UIView {
private struct OnClickHolder {
static var _closure:()->() = {}
}
private var onClickClosure: () -> () {
get { return OnClickHolder._closure }
set { OnClickHolder._closure = newValue }
}
func onTap(closure: #escaping ()->()) {
self.onClickClosure = closure
isUserInteractionEnabled = true
let tap = UITapGestureRecognizer(target: self, action: #selector(onClickAction))
addGestureRecognizer(tap)
}
#objc private func onClickAction() {
onClickClosure()
}
}
Usage:
override func viewDidLoad() {
super.viewDidLoad()
let view = UIView(frame: .init(x: 0, y: 0, width: 80, height: 50))
view.backgroundColor = .red
view.onTap {
print("View Tapped")
}
}
