This is unfortunate. I think visionOS is amazing design. Unreal is emerging as better platform for aerospace and mechanical engineering. Also, recent Unity pricing may be out of reach for many, Unity pricing model unreal for learning full functionality. I hope Apple and Unreal can get along.

I agree. We need all these technologies to move the needle for 3d AR/VR and visionOS. I hope Apple and Unreal can just get along. Recent Unity pricing is unreal ;)
