I've made 3 different videos, at three different locations, and each time have had the same results (and yes, my location in downtown Seattle has location support). One of the videos was done indoors, and reading further i see that probably won't work since the geolocation is only outside, but the other two are outdoors.
I make the recording as per the Explore ARKit 5 WWDC21 session. I save and airdrop it to my Mac (mini 2020, m1). I edit the scheme to use ARKit and select the appropriate .mov file. The app loads onto my debugging device (takes a while for the movie to upload) and then the app launches with the initial white screen then it suddenly switches to a black screen and that's where it stays (after the initial time, when it asked for permission to use camera). All three videos result in the same effect.
The iPhone I'm using to record in Reality Composer is on the iOS 15 beta, as is the device I'm using for debugging (iPad with ios 15 beta). I'm running MacOS 12 beta on my mini and using Xcode 12.5 beta.
I would really like to get this to work, it's really difficult to test where i work, i'm in a very tall building.
Thanks!
Well, it suddenly occurred to me that I am using my iPhone (11 Pro Max, no LIDAR) rather than my iPad (12.9 Pro, 4th gen, LIDAR) to record the video. I recorded this time with the iPad, and the black screen issue is gone; I will continue to test to make sure the rest works.
