Custom MKAnnotationView want to be tapped again - swift

Question

I'm having problems with my custom MKAnnotationView.
I download the coordinate where to place it from my REST api and I place the pin on map with this code:
private func refreshMapView(andCenterMap: Bool){
DispatchQueue.main.async { [weak self] in
guard let self = self else {
return
}
self.mapView.addAnnotations(self.spotsArray)
if andCenterMap {
self.centerMap(at: self.mapView.userLocation.coordinate)
}
}
}
Ones the pin is placed I zoom automatically the map.
Here the code for the custom annotation creation:
func mapView(_ mapView: MKMapView, viewFor annotation: MKAnnotation) -> MKAnnotationView? {
// Do not touch the annotation of the user location
if annotation.isKind(of: MKUserLocation.self){
return nil
}
let annoIdentifier = "SPOT"
var annotationView: MKAnnotationView?
if let dequeued = mapView.dequeueReusableAnnotationView(withIdentifier: annoIdentifier) {
annotationView = dequeued
}else{
let av = MKAnnotationView(annotation: annotation, reuseIdentifier: annoIdentifier)
annotationView = av
}
// Changing the image of the pin
annotationView!.annotation = annotation
if let image = UIImage(named: "map_pin") {
annotationView!.image = image
let deltaY = image.size.height/2
annotationView!.centerOffset = CGPoint(x: 0.0, y: -deltaY)
}else{
annotationView!.image = nil
}
return annotationView
}
As you can notice, my custom pin is using this image (#1x, #2x, #3x)
Ones tapped I want to show the "detail view" and I use the annotation as a sender in order to have all the information I need on the next view.
Here the code:
func mapView(_ mapView: MKMapView, didSelect view: MKAnnotationView) {
guard let ann = view.annotation else {
return
}
if ann.isKind(of: MKUserLocation.self){
return
}
self.performSegue(withIdentifier: "showDetailSegue", sender: ann)
}
So I present all the data I need to and I can go back to the "map view".
The problem is:
In the map view, if I want to select the same annotation again, this is not tappable anymore.
I can see it (in the right place) but I can select it again only if I zoom a little bit and I tap "around" the annotation.
Any suggestione how to solve this issue?
Thanks in advance!

Add this end of didSelect
mapView.deselectAnnotation(ann,animated:false)
