What happened to the geometryType enum in 200.0?

In 100.0 you could decide the type of a geometry via a GeometryType enum, but that doesn't seem to exist in 200.0.

Hope you don't mind, I moved this question to the new Swift Maps SDK Questions forum.

In 200.x we get rid of the previous geometryType property of a geometry, and rely on the metatype of a type, to better follow Swift conventions. Metatypes are used extensively throughout the standard library.

Below is the comparison between the old and new way.

// 100.x switch geometryType { case .point: return "Point" case .polyline: return "Polyline" case .polygon: return "Polygon" default: return nil } // 200.x switch geometry { case is Point: return "Point" case is Polyline: return "Polyline" case is ArcGIS.Polygon: return "Polygon" default: return nil } // or sth like… let geometryType: Geometry.Type = ... switch geometryType { case is Point.Type: print("Point!") default: print("Not Point.") }

A 100.x sample snippet that shows how to switch the geometryType property
A 200.x sample snippet that shows how to add a convenience extension to the Geometry type to decide what specific geometry it is
