Same problems here. Get the error when adding any nodes to the scene. Also performance is bad. Xcode 12.0.1 on Catalina 10.15.7

That’s really bad news for AR. RealityKit might be the successor of SceneKit but it lacks of so much functionality, creating custom geometry is just one example. Therefore the decision to stop developing SceneKit is hurting so many developers. Just give us all the LIDAR features we need to develop great apps with SceneKit!!

Same here since iOS 14. Weird is that my Universal Links are still working as well as saving passwords to the keychain/associate domain. So basically my Associate Domain setup is still ok and only strong passwords is not working.

This issue is resolved with the latest iOS / iPadOS 15 beta release
