Precisely what is the difference between measurements from the LiDAR camera depth data and that provided by the TrueDepth camera? Where is the camera selection done so I can examine the code that sets up the LiDAR camera?

Why are there differences between the Sample application in the download and the code presented in the video? Specifically there are different Imports. I noticed that when I made references to some of the AR functions in. change I made it would not compile clean until I added an import of the ARKit and the Reality Kit even though both are in the RoomPlan import. Does the scope of definitinons get limited to that of the Imported symbols?

I have some confusion over the definition of MediaType versus DeviceType on the calls. It seems to me that because of similarities between the various cameras and the vague dichotomy between TrueDepth and LiDARData for measuring Depth there may be some need for refinement of the calls. My own preference would be to pass an Attribution Mask based on the bit position of the various characteristics of the device and having the bits prioritized so the BEST selection of the available devices would be chosen. For example With True Depth and LiDAR cameras both have depth data but the LiDAR is preferrable for accuracy reasons but some applications could get by with the photogrammetry mode True Depth camera if the LiDAR camera was unusable for some reason. I could see an option that said "Depth but no LiDAR" being selected. The same thing would be true for telephoto lenses versus combined with Wide or Ultrawide (or Hyper-Wide later). Audio streaming would have the same kind of issues with performance levels for input and output being narrowly defined. The question also arises why Device Type allows an array to be passed but not Media Type. It would seem reasonable for both.
