A workaround suitable for testing is to temporarily change the Bundle Identifier of your app. This way your phone/simulator will treat that app as a new app for which the cache doesn't exist yet.

@tsugar thanks for your tips from the practical point of view, extremely valuable :) We’re actually interested in interiors only and using ARKit+LiDAR for that, but this new API makes the photogrammetry so easy that it’s tempting to rethink which path to take.

I've submitted it to the ARKit team as Feedback FB10771463: "ARSession Replay doesn't work when recorded in Reality Composer with Location Recording ON".

Same here, the warnings are not showing up when using a legacy starting project (using storyboards). I think it's relevant for anyone transitioning to Swift UI gradually with their projects.

It's there! https://developer.apple.com/documentation/RealityKit/guided-capture-sample
