known bug with ios15 and realitykit anchorEntity(anchor:x) ref: https://developer.apple.com/forums/thread/699266

I need this too. Apple please respond quickly, we have product to build.

Why does a dialog pop up that requires install of new components? This is a) rude to force an update b) this is an upgrade not a component install which is deceptive c) disrupting engineering productivity time loss due to hours of down time d) just mean.

just upgraded my ipadOS app to iOS15 and the AR part of the app is now completely broken. literally no AR functionality works. other than that, an awesome upgrade;) I verified I'm not crazy by installing the same app to iPad8 running iOS14.8 and my AR functionality works fine. broken environment: xcode13, ios15 (prod release), ipadPro working environment: xcode13, ios14.8, iPad8 I think this is worth a zoom meeting to demo my findings with the apple dev team.

The anchorEntity is properly composed based in an ImageDetect (ARImageAnchor) in the func session() code. This code has been in use for 8months, working correctly. Scale is not a problem, I validate that by not doing SceneStart hidden for the Object, and just show/hide the object (isEnabled true/false). Which works fine. You can quickly reproduce this in the HelloAR app by creating a single behavior for the Box object with SceneStart hidden. Then in the boilerplate code add Box.isEnabled = true. And then you reproduce the problem. Take the same object remove hide from SceneStart and put in a Notification behavior, fire the notification in code to hide, put a wait in your code for the visual change to be obvious, then run the Box.isEnabled = true and it works correctly.

Environment: xcode 12.5.1, ios 14.8, ipadPro

Last update was about a year ago with RC 1.5. If there are no additional updates is RC feature complete or is Apple staffing and advancing the product?
