@interface MGLShapeCollection : MGLShape
MGLShapeCollection object represents a shape consisting of zero or more
distinct but related shapes that are instances of
MGLShape. The constituent
shapes can be a mixture of different kinds of shapes.
MGLShapeCollection is most commonly used to add multiple shapes to a single
MGLShapeSource. Configure the appearance of an
MGLVectorSource’s shape collection collectively using an
MGLSymbolStyleLayer object, or use multiple instances of

You cannot add an
MGLShapeCollection object directly to a map view as an
annotation. However, you can create individual

shapes array and add those
annotation objects to the map view using the
