GMSMarker to CKAnnotation about clusterkit HOT 1 CLOSED

Whoever is struggling with this in the future:

1. Create annotation that inherits from NSObject and CKAnnotation

class Annotation: NSObject, CKAnnotation{
    weak var cluster: CKCluster?
    
    var coordinate: CLLocationCoordinate2D
    var name: String!
    init(coordinate: CLLocationCoordinate2D, name: String){
        self.coordinate = coordinate
        self.name = name
    }
}

2. Make array: var annotations:[Annotations] = []

3. Append the annotations array and then assign this array to clusterManager self.mapView.clusterManager.annotations = self.annotations

from clusterkit.
