I’m a bit stuck on placing an anchor entity within an immersive space on another wall with drag gestures.
What I want:

1. User enters an ImmersiveSpace
2. A photo frame appears before them sticks to the wall
3. User can then move the frame entity to another vertical wall using DragGesture().

The issue I’m having is not able to move the frame entity to another vertical wall with drag gesture. I want to move the entity on the same wall and move to the other vertical wall and restrict to place on the corners.

Here’s my code so far.

@State private var anchor = AnchorEntity()
var body: some View {
        RealityView{ content in                        
            let wallAnchor = AnchorEntity(.plane(.vertical, classification: .wall, minimumBounds: SIMD2<Float>(0.1, 0.1)), trackingMode: .once)
            let material = UnlitMaterial(color: .clear)
            let planeEntity = ModelEntity(mesh: .generatePlane(width: 0.1, height: 0.1), materials: [material])
            
            planeEntity.name = "plane"
            async let textEntity = ModelEntity(named: “Photo”)
    
            if let textEntity = try? await textEntity {
               planeEntity.addChild(textEntity)
                appleWatch = textEntity
                wallAnchor.addChild(planeEntity)
                anchor = wallAnchor
            }
            
            wallAnchor.components.set(InputTargetComponent(allowedInputTypes:.indirect))
            wallAnchor.generateCollisionShapes(recursive: true) 
            content.add(wallAnchor)
        }    .gesture(
                    DragGesture()
                        .onChanged { value in
                            let startPosition = startPosition ?? anchor.position
                            self.startPosition = startPosition
                      
                            let delta = SIMD3<Float>(
                                Float(value.translation.width) / 1000.0, 
                                0,
                                Float(value.translation.height) / 1000.0 
                            )
                            anchor.position = startPosition + delta
                        }
                        .onEnded { _ in
                            startPosition = nil
                        }
                )
