ios – Clustering annotations with Mapbox



I try to implement clustering in Mapbox for iOS and literally use this example from the Mapbox website

It works fine, but I would like to use simple MGL notes to place on the map and link them if they is too close.

I read here that MGLShapeSource not only accepts external geoJSON, but other sources, such as polylines and annotations. But when I add it to notes, no grouping occurs, I see only many of my markers from my annotation event:

la source = MGLShapeSource (identify: "clusteredParkings, forms: annotationsArray, options: [.clustered: true, .clusterRadius: 20] )

When I switch source back to geoJSON, it works again for clusters.
Btw there are no errors or warnings.

What am I doing wrong? Does anyone have a working example of Mapbox clustering with MGLAnnotations rather than geoJSON source file?
