You can use AGSRequestConfiguration to log some debug info to the console. Try something like this: let locatorTask = AGSLocatorTask(url: URL(string: "https://my-server/services/GeocodeServer/")!) if let gc = AGSRequestConfiguration.global().copy() as? AGSRequestConfiguration { gc.debugLogRequests = true locatorTask.requestConfiguration = gc } That should output the request for you. Please note that you should not log this debug info in a release version of your app. There is a performance hit to this logging and you should disable it in production and testing. ... View more

Hi. Image tiled layers are designed for efficient display and don't have any backing information built in. A couple of thoughts… Do you have access to the source data as feature data to query against? Another option would be to export an image snapshot of the map view using exportImage(), and convert the lat/lon from an AGSPoint into a screen location using locationToScreen(), then read the pixel value of the image for the CGPoint you get back. ...

Hi. The identify calls available on AGSMapView are focused on interaction so revolve around tapping on the screen. To search using an arbitrary geometry, you will have to call Query on the feature tables that you're interested in. This assumes that the "symbol markers" you're referring to represent features in a feature layer. Take a look a this conceptual doc: hosted-feature-layers Also take a look at this sample, which references a feature table (in this case, an AGSServiceFeatureTable), sets up an AGSQueryParameters, and then calls queryFeatures using the parameters, which is returned a set of features. You would do the same, except that instead of setting a whereClause on the parameters, you would set the geometry to the geometry from the sketch editor, and spatialRelationship to .within. If the "symbol markers" are graphics in a graphics overlay, then you'll have to iterate over each graphic in the graphics overlay and for its geometry use the AGSGeometryEngine.geometry(graphicGeom, within: sketchGeom) to narrow it down. This code could help. It shows both GraphicsOverlay and Feature Layer approaches. I haven't actually run it, but it compiles 🙂 extension AGSGraphicsOverlay { func getGraphics(within searchPolygon: AGSPolygon) -> [AGSGraphic] { let graphicsWithinGeometry = (graphics as? [AGSGraphic])?.filter { graphic in guard let graphicGeometry = graphic.geometry else { return false } return AGSGeometryEngine.geometry(graphicGeometry, within: searchPolygon) } return graphicsWithinGeometry ?? [] } } extension Array where Element == AGSGraphicsOverlay { func getGraphics(within searchPolygon: AGSPolygon) -> [AGSGraphicsOverlay: [AGSGraphic]] { var results = [AGSGraphicsOverlay: [AGSGraphic]]() for overlay in self { results[overlay] = overlay.getGraphics(within: searchPolygon) } return results } } extension AGSMap { func queryFeatures(within searchPolygon: AGSPolygon, completion: @escaping ([AGSFeatureLayer: Result<AGSFeatureQueryResult, Error>]) -> Void) { // Create a store for all the results coming back from each feature layer var results = [AGSFeatureLayer: Result<AGSFeatureQueryResult, Error>]() // Create a Dispatch Group to coordinate the async Query calls against all the feature layers. let coordinator = DispatchGroup() // Query each feature layer in parallel, collecting all the query results in the `results` variable. for layer in operationalLayers.compactMap({ return $0 as? AGSFeatureLayer }) { guard let table = layer.featureTable else { continue } // Find all features in the feature layer that are within the search polygon let params = AGSQueryParameters() params.whereClause = "1=1" params.spatialRelationship = .within params.geometry = searchPolygon coordinator.enter() table.queryFeatures(with: params) { [layer] result, error in defer { coordinator.leave() } if let error = error { results[layer] = Result.failure(error) } else if let result = result { results[layer] = Result.success(result) } else { assertionFailure("No result OR error - that shouldn't happen") } } } // Once all the queries have completed, execute this code… coordinator.notify(queue: .main) { completion(results) } } } You could then call that with something like this… if let searchGeom = sketchEditor.geometry as? AGSPolygon { map.queryFeatures(within: searchGeom) { results in for (layer, queryResponse) in results { print("Got result for \(layer.name)") switch queryResponse { case .success(let queryResult): print("Found \(queryResult.featureEnumerator().allObjects.count) features") case .failure(let error): print("There was an error querying the layer: \(error.localizedDescription)") } } } if let results = (mapView.graphicsOverlays as? [AGSGraphicsOverlay])?.getGraphics(within: searchGeom) { for (overlay, graphics) in results { print("Found \(graphics.count) graphics in overlay \(overlay)") } } } Again, I haven't had a chance to run this code, but it should give you an idea of how to do this. ...
