I've got pins placed on a map and when I tap on them I'm calling the `didSelect`. The function only gets called the first time the pin is tapped, and after that it's not called on that same pin again unless I select another pin and then come back and tap it.

What that sounds like to me is the pin is being selected, and `didSelect` can only be called in unselected pins, so when I go tap on another pin it's deselecting the first pin and making it tappable again.

```
func mapView(_ mapView: MKMapView, didSelect view: MKAnnotationView) {
    view.isSelected = false
}

```

I don't understand why the above code does not work. 

How can I allow my annotations be tapped more than one time in a row?
