MGLPolygonStyleAnnotation coordinates do not conform to the GeoJSON spec

[TimothySealy]

According to the GeoJSON spec the coordinates of a Polygon "MUST be an array of linear ring coordinate arrays". This translates to an array of arrays of points. According to the example you have to pass an array of points to the MGLPolygonStyleAnnotation. It seems to be missing an additional (outer) array.

MGLPolygonStyleAnnotation seems to have a constructor (declaration, definition) that accepts interior polygons (holes) as a separate parameter. Perhaps that is what you're looking for?

(instancetype)initWithCoordinates:(const CLLocationCoordinate2D *)coordinates count:(NSUInteger)count interiorPolygons:(NSArray<MGLPolygonFeature *> *)interiorPolygons

@skreborn Thanks for the clarification. I overlooked the interiorPolygons parameter.

Happy to help. Should this issue be closed then?

Closing this up with two remarks:

1. I think it would be a good idea to clarify the usage of the interior polygons in the documentation.
2. A constructor overload which only takes polygons (where the first polygon is the outer and the rest inner polygons) would be appreciated.
