Swift Custom Annotation does not get select - swift

Question

I have a custom annotationView on my map, when I select the custom annotation i want to create a action and pass the annotation data to another view. The best way for it to work I would have to use the built in func didSelect. When i do select the custom annotation nothing thing happen. Im not show why the didSelect function did not get called thank you in advance.
class RquestCustomPointAnnotation:MKPointAnnotation {
var image: String!
}
func placeRquestByUsersOnMap(){
//retrieve item from firebase
var markerArray = [MKPointAnnotation]()
let path = "rquest/frontEnd/posts/userCreatedPost"
self.childRef(path).observe(.childAdded, andPreviousSiblingKeyWith: {snapshot, _ in
//get status
if let status = snapshot.childSnapshot(forPath: "status").value as? String {
if status == "pending"{
let indentifier = "rquest"
if let coordinate = snapshot.childSnapshot(forPath: "coordinate").value as? NSDictionary {
let lat = coordinate["lat"] as! Double
let long = coordinate["long"] as! Double
let location = CLLocationCoordinate2D(latitude: lat, longitude: long)
let point = RquestCustomPointAnnotation()
let rquestView = MKAnnotationView(annotation: point, reuseIdentifier: indentifier)
point.image = "22"
let key = snapshot.key
point.coordinate = location
point.accessibilityValue = key
point.accessibilityLabel = "Rquest"
markerArray.append(point)
self.mapView.addAnnotation(rquestView.annotation!)
//create an obserarver to check if it is
let paths = "rquest/frontEnd/posts/userCreatedPost/\(key)/"
self.childRef(paths).observe(.childChanged, andPreviousSiblingKeyWith: { (snap, _) in
if snap.key == "status" {
if let status = snap.value as? String {
if status != "pending" {
for i in markerArray {
if i.accessibilityValue == key {
self.mapView.removeAnnotation(i)
}
}
}
}
}
})
}
}
}
})
}
func mapView(_ mapView: MKMapView, viewFor annotation: MKAnnotation) -> MKAnnotationView? {
if annotation is RquestCustomPointAnnotation {
let reuseIdentifier = "rquest"
var annotationView = mapView.dequeueReusableAnnotationView(withIdentifier: reuseIdentifier)
if annotationView == nil {
annotationView = MKAnnotationView(annotation: annotation, reuseIdentifier: reuseIdentifier)
annotationView?.canShowCallout = true
} else {
annotationView?.annotation = annotation
}
let customPointAnnotation = annotation as! RquestCustomPointAnnotation
annotationView?.image = UIImage(named: customPointAnnotation.image)
return annotationView
}
}
func mapView(_ mapView: MKMapView, didSelect view: MKAnnotationView) {
print("did select")
}

You have canShowCallout set to true. So, when you tap on it, do you want callout or have it call didSelect? (Usually you'd do one or the other, but not both.) And are you seeing your callout?
I notice a curious behavior that if (a) the annotation doesn't have a title, and (b) the annotation view's canShowCallout is true, then not only can it not show the callout, but it also prevents the didSelect from being called.
You may either want to turn canShowCallout to false, or make sure your annotation has a title.
