How to get the lat/long in MapBox iOS SDK after drag&drop
I'm using drag&drop the same way as in the official example of MapBox:
https://www.mapbox.com/ios-sdk/maps/examples/draggable-views/
I can't find a way to get the lat/long of the dragged annotation after dropping.
There is no delegate. Neither in MGLMapViewDelegate nor in any other delegate.
MGLAnnotationView has some dragState-members which do not match the lat/long-request.
https://www.mapbox.com/ios-sdk/api/4.6.0/Classes/MGLAnnotationView.html
When I use initWithAnnotation:reuseIdentifier: instead of initWithReuseIdentifier: the MGLAnnotationView has its annotation-property set correctly. But the annotation.coordinate does not get updated.
https://www.mapbox.com/ios-sdk/api/4.6.0/Classes/MGLAnnotationView.html#/c:objc(cs)MGLAnnotationView(im)initWithAnnotation:reuseIdentifier:
So how can I get the lat/long after dropping?

If I'm understanding you correctly, this should be as simple as checking the annotation associated with the annotationView once the dragging has finished.
Have you tried something like the following inside your draggable MGLAnnotationView subclass?
let newLatitude = self.annotation?.coordinate.latitude
let newLongitude = self.annotation?.coordinate.longitude
-- allowing for the usual optional checks, etc. I have these lines inside the endDragging() method.

Yes you are right. During MGLAnnotationViewDragStateDragging the coordinate is not updated. But MGLAnnotationViewDragStateEnding the coordinate of the annotation gets updated.

The coordinate of the associated annotation gets updated only at ending not during dragging.
case MGLAnnotationViewDragStateDragging:
NSLog(@"%@ / %@", @(self.annotation.coordinate.latitude), @(self.annotation.coordinate.longitude));
break;
case MGLAnnotationViewDragStateEnding:
case MGLAnnotationViewDragStateCanceling:
NSLog(@"endDragging: %@ / %@", @(self.annotation.coordinate.latitude), @(self.annotation.coordinate.longitude));
[self endDragging];
break;
