Playing with ARObjectAnchor and I'm finding out it doesn't seem to handle moving objects very well. When I move the object it is lost and gets re-detected a few seconds later. Is there any way to track it continuously?

For example, if I scan a box, I would like the user to be able to pick it up and move it, then have AR objects follow it. Is it possible to do this real time or does ARObjectAnchor just not update that often?

I had a similar problem with ARImageAnchor initially but discovered changing some settings greatly increased the update rate. Is there something I can do to speed up ARObjectAnchor?

When ARKit detects a reference object for the first time, it creates an ARObjectAnchor at that location. After that, the object's position is not continuously updated. You could manually remove that anchor from the session to initiate a re-detection as soon as the object is back in the view. However, unlike images, objects are not tracked in real time. Please feel free to send a feature request on http://feedbackassistant.apple.com/.

As you mentioned correctly, ARImageAnchors are updated 60 times per second when you set maximumNumberOfTrackedImages to a value greater than 0.
