my custom annotation can not cast down CKCluster about clusterkit HOT 5 CLOSED

First your CafeShopAnnotation should adopt the CKAnnotation protocol.
Then, you should add your annotations to the mapView.clusterManager.annotations (not to the mapView)

from clusterkit.

Cool brother, but i have another question.

Mapview annotation view only have black view , why ?

    func mapView(_ mapView: MKMapView, viewFor annotation: MKAnnotation) -> MKAnnotationView? {
       
        let annotationView = mapView.dequeueReusableAnnotationView(withIdentifier: "annotation") ??
            MKAnnotationView(annotation: annotation, reuseIdentifier: "annotation")
       if annotation.isKind(of: MKUserLocation.self) {
            return nil
            
        } else if let cluster = annotation as? CKCluster {
            
            if cluster.count > 1 {
                annotationView.canShowCallout = true
                annotationView.image = UIImage(named: "cluster")
            } else {
                annotationView.canShowCallout = true
                annotationView.image = UIImage(named: "marker")
            }
        
        }
        return annotationView
    }

And i see your website ClusterKit DEMO , have a message count on annotation view, how to do that ?

from clusterkit.

For the count in cluster, please refer to #11
All the view are black even if you zoom in?

NB: canShowCallout of a cluster view should be set to false if you wan to zoom in on touch.

from clusterkit.

Yes , even zoom in, and after zoom in limited i check the cluster count return 2.

didSelect view.Annotation only coordinate have value, title and subtitle are nil.

from clusterkit.

title and subtitle are nil because it's a cluster annotation.
Are you sure that your data set has no duplicates, or annotations with the same position ?
