I am an indie developer and I've put a lot of effort to impelent my game using SceneKit. I've choosen SceneKit so that my game would be small and run without any additional external graphics engines and because it was developed by Apple, so I thought that it will never disappear. Now I'm not sure what will happen with the RealityKit in the future, maybe at some point in time it will be also deprecated? It will take me a lot of time to rewrite my game.

Just to name one it's missing for example SCNProgram and attaching it to the material's program property.

I've just started migration to RealityKit and I see at least one issue - SCNProgram is not available.

Thanks, I understand that, but it doesnt say when SceneKit will be removed.

Thanks for the clarifications.

Thanks for this answer.

Handling gestures inside of the RealityView + SwiftUI and setting up the camera is not possible. As soon as I add PerspectiveCamera then TapGesture().targetedToAnyEntity() stops to work, it's the same even if I move an Entity to far away from the default camera. Based on my current knowledge RealityKit is not replacement for SceneKit and I'm considering different engines right now, because who knows maybe in 5 years RealityKit is deprecated and I will have to rewrite again to something else.
