SceneView Not Rendering Graphics or 3D Map When Using .geoTracking in World Scale AR (Swift iOS)

nvsraju0979 — Mon, 18 Aug 2025 12:52:45 GMT

I'm working on an AR project using ArcGIS Runtime SDK for iOS with a world-scale ARSCNView setup. I have a SceneView configured and everything works fine when using .worldTracking mode — the 3D map and graphics load and display as expected.

However, when I switch the tracking mode to .prefergeoTracking or .geoTracking using:

    WorldScaleSceneView (trackingMode: .preferGeoTracking){ proxy in }

the scene goes blank — no graphics or 3D map content appears. I’ve already ensured location permissions are granted, and the GPS is working. But still, the scene remains empty when using geo-tracking.

Has anyone else faced this issue? Is there something additional I need to configure for .geoTracking to render the scene correctly?

Any help or guidance would be greatly appreciated!

Thanks in advance!

Hi @nvsraju0979,

Thanks for your question. There are a few possibilities why 3D content may appear using the `worldTracking` tracking mode and not when using `geoTracking`.

The `geoTracking` mode uses the `ARGeoTrackingConfiguration` which has a few requirements:
- The device used and geographic area must support geotracking.
- The ARCoachingOverlayView dismisses and geotracking localization completes.
- The trackingMode should be set once. Updating the trackingMode after the WorldScaleSceneView is initialized is not supported.

For the scene view and graphics to render:
- Check if there is a required API key that is not set.
- Add the scene view graphics after geoTracking localization.
- To check this, use the `WorldScaleSceneView.onGeoTrackingStatusChanged(perform:)` closure. This code snippet shows an example of adding a graphic around the initial location once geoTracking is localized.

@State private var isLocalized = false var body: some View { WorldScaleSceneView(trackingMode: .geoTracking) { _ in SceneView(scene: scene, graphicsOverlays: [graphicsOverlay]) } .onGeoTrackingStatusChanged { geoTrackingStatus in isLocalized = geoTrackingStatus.state == .localized } .task(id: isLocalized) { guard isLocalized else { return } let locationManager = CLLocationManager() if locationManager.authorizationStatus == .notDetermined { locationManager.requestWhenInUseAuthorization() } try? await locationDataSource.start() // Retrieve initial location. guard let initialLocation = await locationDataSource.locations.first(where: { @Sendable _ in true }) else { return } // Put a circle graphic around the initial location. let circle = GeometryEngine.geodeticBuffer(around: initialLocation.position, distance: 20, distanceUnit: .meters, maxDeviation: 1, curveType: .geodesic) graphicsOverlay.addGraphic(Graphic(geometry: circle, symbol: SimpleLineSymbol(color: .red, width: 3))) // Stop the location data source after the initial location is retrieved. await locationDataSource.stop() }
