Starting with iOS 18.0 beta 1, I've noticed that RealityKit frequently crashes in the simulator when an app launches and presents an ARView.
I was able to create a small sample app with repro steps that demonstrates the issue, and I've submitted feedback: FB16144085
I've included a crash log with the feedback.
If possible, I'd appreciate it if an Apple engineer could investigate and suggest a workaround. It's awkward to be restricted to the iOS 17 simulator, which does not exhibit this behavior.
Please let me know if there's anything I can do to help.
Thank you.
