Anything that speeds up the development cycle is interesting and the Unity ARKit Remote manages to avoid having to go through Xcode every time around the loop. Provided the app can be run in the Editor, any changes to objects or scripts can be tested very quickly. The iPhone (in this case) runs a special remote app that passes ARKit data back to the app running in the Editor. You don’t see any of the Unity stuff in the phone itself, just the camera feed. The composite frames are shown in the Editor window as above.
