Discussion
Depending on the session configuration, ARKit may automatically add anchors to a session, such as the origin of the world coordinate system and detected planes. ARKit also calls this method to provide visual content for any ARAnchor objects you manually add using the session's add(anchor:) method.
You can implement this method to provide a new SKNode object (or instance of any system or custom SKNode subclass) you plan to use as a visual representation of the anchor.
Note that ARKit controls the node's position, rotation, and scale to simulate a billboarded 3D effect even for 2D sprites. If you provide a SKTransformLayer node, ARKit applies a 3D transformation.
Alternatively, if you do not implement this method, ARKit creates an empty node, and you can implement the view(_: method instead to provide visual content by adding children to that node.
