Description

Environment

  • Xcode version: 15.4
  • visionOS version: 2.0
  • Devices affected: Vision Pro
  • Maps SDK Version: 11.6.1

Observed behavior and steps to reproduce

In visionOS, I'm trying to apply a 3d rotation effect to have the map take up the space on the "floor" of a volume, but when i do this, the drag and zoom gestures become unusable. A small movement makes the panning go haywire and it infinitely scrolls as fast as possible. There is no control at all.

import SwiftUI
import RealityKit
import RealityKitContent
@_spi(Experimental) import MapboxMaps

struct VolumeView: View {
    init() {
        MapboxOptions.accessToken = "<redacted>"
    }
    var body: some View {
        GeometryReader3D { geometry in
            MapboxMapView()
                .ignoresSafeArea()
                 .rotation3DEffect(
                     .degrees(90),
                     axis: (x: 1.0, y: 0.0, z: 0.0)
                 )
                 .offset(z: geometry.size.depth / 2)
                 .offset(y: geometry.size.height / 2)
        }
    }

}

struct MapboxMapView: UIViewRepresentable {
    private let arrifana = CLLocationCoordinate2D(latitude: 37.292182, longitude: -8.863332)
    
    func makeUIView(context: Context) -> MapView {
        let gestureOptions = GestureOptions(pitchEnabled: false)
        let cameraOptions = CameraOptions(center: arrifana, zoom: 10, pitch: 70)
        
        let mapView = MapView(frame: .zero)
        mapView.mapboxMap.setCamera(to: cameraOptions)
        mapView.gestures.options = gestureOptions
        
        return mapView
    }
    
    func updateUIView(_ uiView: MapView, context: Context) {}
}

#Preview(windowStyle: .automatic) {
    VolumeView()
}


Expected behavior

Drag and zoom behaviour should be consistent regardless of 3D translation of the Map View

Research direction

Start with the MapboxMapView makeUIView entry point and the GestureOptions configuration shown in the report, then reproduce the issue in the provided VolumeView on visionOS. The work is done when panning and zooming remain controllable and consistent after the MapView is rotated and translated in the 3D volume.
