Any update regarding this issue? I can't open on my iPhone (iOS 15.2.1) reality files generated on my iPad (14.8.1) with Reality Composer. I have tried opening the reality composer file on my iPhone and exporting it, but I can't open the resulting reality file.

Thanks a lot. Please let me know in this thread if you get any update regarding this issue. I would really appreciate it. Could you just confirm that I can still work on my project on Reality Composer on my iOS 14 device and that I won't have to start the project again on an iOS 15 device once the problem is solved?

Our issue seems to be solved now, after changing the "Parent app identifier" in the .entitlements file of the appclip to match the bundle id of the app.

Please help, this is really hindering us from delivering our project. I have tried creating a .reality file on Reality Composer on my iPhone 12 Pro after updating it to iOS 15.2 and the exported file displays the same error message saying “the object cannot be opened”. I have also tried to update my iPhone X to iOS 15.3 and the problem is still there with the latest version of iOS.

Thank you, I wasn't entirely sure this was the same problem, since in my case reality files generated on iOS 15 devices won't open on the very same device.

Hi, thanks for your answer. However, since our SceneView is an ARCNView, we can't seem to access the SCNSceneRenderer methods. We only have access to the "Prepare" method. We tried implementing it to preload the scene and it assets. It seems to be doing something because we get a significantly longer freeze at the start of the experience, however we still experience the same fps drops during the experience when our objects appear for the first time.

Good evening, I have a question related to your post : https://developer.apple.com/forums/thread/699227 Is there any tutorial on how to use the prepareObject:shouldAbortBlock: and the prepareObjects:withCompletionHandler methods? In our case the SceneView is an ARCNView, so we can't seem to access the SCNSceneRenderer methods.
