I would suggest creating multiple ClusterManagers.

If you are referring to one dataset but different UIs, you can customize the UI of the cluster view itself using the delegates.

thank you so much!!

ok , I have add two ClusterManagers,but i dont know how to make difference color at cluster

my problem is at viewFor function if i want to make diffenence cluster color, its change code in viewFor function ?

this my code

lazy var carManager: ClusterManager = { [unowned self] in
    let carManager = ClusterManager()
    carManager.delegate = self

    carManager.maxZoomLevel = 17
    carManager.minCountForClustering = 5
    carManager.clusterPosition = .nearCenter

    return carManager
}()

lazy var manager: ClusterManager = { [unowned self] in
    let manager = ClusterManager()
    manager.delegate = self

    manager.maxZoomLevel = 17
    manager.minCountForClustering = 1
    manager.clusterPosition = .nearCenter

    return manager
}()

my problem is in here if i want to make diffenence cluster color, its change code in here?

func mapView(_ mapView: MKMapView, viewFor annotation: MKAnnotation) -> MKAnnotationView? {

    if annotation is MKUserLocation {
        print("MKUserLocation is nil")
        return nil
    }

    if let annotationCluster = annotation as? ClusterAnnotation {

        print("ClusterAnnotation")
        let index = 0
        let identifier = "Cluster\(index)"
        let selection = Selection(rawValue: index)!
        return mapView.annotationView(selection: selection, annotation: annotationCluster, reuseIdentifier: identifier)
    }
}

If you subclass the annotations, you can differentiate between the annotations added to each manager. Use a different annotation subclass for each manager and check the type when you create the view.

func mapView(_ mapView: MKMapView, viewFor annotation: MKAnnotation) -> MKAnnotationView? {
    if let cluster = annotation as? ClusterAnnotation {
        let child = cluster.annotations.first
        switch child {
        case is SomeAnnotationOne:
            return mapView.annotationView(selection: selection, annotation: child, reuseIdentifier: identifier)
        case is SomeAnnotationTwo:
            return mapView.annotationView(selection: selection, annotation: child, reuseIdentifier: identifier)
        default: break
        }
    }
}
