Hit test does not work for .dae files in the scene

Hit test as described for the geometry models works but does not work for .dae models that have been added to a scene. Stackflow seems to indicate that it is because the node does not have any geometry when the hit test is performed. Is there a method to hit test .dae models? I would like to be able to drag an object once selected. I am using Swift 3.

Have you considered have Xcode convert the .dae file to .scn files?

In the project, select the .dae file, go to the Editor Menu, select:
Convert to cenKit scene file format (.scn)

Thank you. Yes, that method works and appears that it is the simplest solution.
