I have tried it but I get a crash when using observableObject

Hello, did you found out how to do it ? I have the same question. Thank you

Hi. I'm having the same issue and I have done two web pages examples one using Google Maps and another using MapKit JS exactly with the same datapoint and using on MapKit JS MarkerAnnotation following the suggestion on this trend. The diference in performance it's of several orders of magnitude in favor of Google. The use case its the same in both - reading a Json web php with datapoints ... In MapKit JS I'm doing : function displayLocation(map, location) { var coordinates = new mapkit.Coordinate(parseFloat(location.lat), parseFloat(location.lng)); var annotation = new mapkit.MarkerAnnotation(coordinates, { title: location.device, subtitle: location.time , color: 'red' }); map.addAnnotation(annotation); }; In my opinion the performance should be at least the same ... Any comments ?
