I am creating an Augmented Reality iOS (Not VisionOS) app using scenes created in Reality Composer Pro.
I'd like my code to send a notification to a RCP scene that plays a timeline. The RCP interface has the option to set up a behaviour for this purpose:
This Forum thread https://developer.apple.com/forums/thread/756978 suggests the code I need for sending a notification is:
name: NSNotification.Name("RealityKit.NotificationTrigger"),
object: nil,
userInfo: [
"RealityKit.NotificationTrigger.Scene": scene,
"RealityKit.NotificationTrigger.Identifier": "HideCharacter"
]
)
but the 'scene' var needs to point to the relevant RCP scene, which is loaded within a UIViewRepresentable ARView (because even in iOS26 it seems RealityKit/RealityViews aren't quite ready for AR use) and I can't work out how to correctly access it. Examples in the link above are for working with RealityKit and VisionOS only.
Code for loading the scene is as follows. How can I get the notification code above to be situated in a separate SwiftUI View and send the notification to the RCP scene?
typealias UIViewType = ARView
func makeUIView(context: Context) -> ARView {
// Create an ARView
let arView = ARView(frame: .zero)
// Configure it
let arConfiguration = ARWorldTrackingConfiguration()
arConfiguration.planeDetection = [.horizontal]
arView.session.run(arConfiguration)
// Load in Reality Composer Pro scene
let scene = try! Entity.load(named:"myScene)", in: realityKitContentBundle)
// Create a horizontal plane anchor
let anchor = AnchorEntity(.plane(.horizontal, classification: .any, minimumBounds: SIMD2<Float>(0.2, 0.2)))
// Append the scene to the anchor
anchor.children.append(scene)
// Append the anchor to the ARView
arView.scene.anchors.append(anchor)
return arView
}
func updateUIView(_ uiView: ARView, context: Context) {
}
}
