Hi,
I'm rewriting my game from SceneKit to RealityKit, and I'm having trouble implementing the following scenario:
I tap on the iPhone screen to select an Entity that I want to drag.
If an Entity was tapped, it should then be possible to drag it left, right, etc.
SceneKit solution:
func CGPointToSCNVector3(_ view: SCNView, depth: Float, point: CGPoint) -> SCNVector3 {
let projectedOrigin = view.projectPoint(SCNVector3Make(0, 0, Float(depth)))
let locationWithz = SCNVector3Make(Float(point.x), Float(point.y), Float(projectedOrigin.z))
return view.unprojectPoint(locationWithz)
}
and then I was calling:
SCNView().hitTest(location, options: [SCNHitTestOption.firstFoundOnly:true])
the code was called inside of the UIPanGestureRecognizer in my UIViewController.
Could I reuse that code or should I go with the SwiftUI approach - something like that:
var body: some View {
RealityView {
....
} .gesture(TapGesture().onEnded {
})
?
I already have this code:
@State private var location: CGPoint?
.onTapGesture { location in
self.location = location
}
I'm trying to identify the entity that was tapped within the RealityView like that:
RealityView { content in
let box: ModelEntity = createBox() // for now there is only one box, however there will be many boxes
content.add(box)
let anchor = AnchorEntity(world: [0, 0, 0])
content.add(anchor)
_ = content.subscribe(to: SceneEvents.Update.self) { event in
//TODO: find tapped entity, so that it could be dragged inside of the DragGesture()
}
Any help would be appreciated.
I also noticed that if I create a TapGesture like that:
TapGesture(count: 1)
.targetedToAnyEntity()
and add it to my view using .gesture() then it is not triggered.
Selecting any option will automatically load the page

Now that SceneKit has been marked as soft deprecated, is there a planned date or timeframe when it will be completely removed from iOS? I’m concerned about how long my existing SceneKit-based game will continue to work, especially as an indie developer without the resources for a quick rewrite to RealityKit.
Hello,
I'm currently working on my first SceneKit game and have encountered an issue related to moving an SCNNode using a UIPanGestureRecognizer.
When I deploy the game to my iPhone via Xcode in debug mode, all interactions are smooth. However, when I stop the debugging session and run the game directly from the device (outside of Xcode), the SCNNode movement behaves inconsistently — it works sometimes smoothly and sometimes not and the interaction becomes choppy. The SCNNode movement is controlled using a UIPanGestureRecognizer.
Do you have any ideas what might be causing the issue?
