I updated XCode to 16 Beta visionOS to 2 Beta iPadOS to 18 Beta and set these to xcode project targets >> General >> Minimum Deployment then in targets >> General >> Framework, Liberies and Embedded Content, Make RealityKitContent only used by visionOS. not sure what exactly make it work but now I can run the project on both iPas and AVP.

I have the same problem here [quote='795031022, Vision Pro Engineer, /thread/757062?answerId=795031022#795031022'] restarting Xcode, deleting DerivedData, and selecting Package Dependencies > Reset Package Caches [/quote] and this is not working for me
