In "Discover ARKit 6" there's a cool demo of setting a point in AR where a picture was taken, and guiding the user there. Is sample code for this available somewhere?
Thanks for your excitement about that app idea. We do not have the sample code, but I recommend going to our Explore ARKit 4 session where we explain how to pick a coordinate in Maps and create an ARGeoAnchor based on it. For alignment with the real world we have the example with the Ferry Building in SF. We followed that exact workflow with the focus square example.
