MKAnnotationView and tap detection

Question

I have a MKMapView. I added a UITapGestureRecognizer with a single tap.

I now want to add a MKAnnotationView to the map. I can

Answer 1

It'd be much easier if we just test the superviews of the touch.view in the gesture delegate:

func gestureRecognizer(_ gestureRecognizer: UIGestureRecognizer, shouldReceive touch: UITouch) -> Bool {
    var tv = touch.view
    while let view = tv, !(view is MKAnnotationView) {
        tv = view.superview
    }
    return tv == nil
}
