One thought. Setting the map on the map view will proceed to load the map. Once its loaded, its spatial reference is fixed and I wonder, because you haven't set a basemap or a spatial reference, whether it's set to something that isn't the same as the WMTS layer. Tiled layers are not reprojected in Runtime so that could lead to you not being able to display the layer. Can you try calling mapView.map = map right after you set map.basemap = Basemap(wmtsLayer)? Or you could create the ArcGISMap with a spatial reference if you know what it should be: https://developers.arcgis.com/android/api-reference/reference/com/esri/arcgisruntime/mapping/ArcGISMap.html#%3Cinit%3E(com.esri.arcgisruntime.geometry.SpatialReference) Do either of those suggestions help?

If you have your point of interest geometries, you could also use GeometryEngine.combineExtents to get the minimal containing envelope. You can then pass that envelope to MapView.SetViewpointGeometryAsync() (that's a shortcut/equivalent to the method that Keith mentioned above).

Any idea why AGSPolygon.fromJSON returns NIL instead of an AGSPolygon? Yes. As I mentioned before, the REST request you're making doesn't just return a geometry. In fact it returns a set of features, including metadata. Each feature contains a geometry, but the full JSON you get back is much more than that, and you're trying to hydrate a geometry from the entire feature set JSON. I strongly recommend that you follow the queryFeaturesAndAddAsGraphics() example method I provide and do not make your own REST requests. It will simplify your life significantly. You can see on line 79 of my example code that I get the polygon of the first feature that's returned. If you need to persist that, you can call toJSON() on it. The JSON you get out of that can be used later to create a new AGSPolygon with fromJSON(). Incidentally, your call to fromJSON() is also ignoring the error that is returned.

Hi. I think you might be overthinking this a bit 🙂 The Runtime SDK takes care of a lot of this stuff for you. Take a look at this sample, and the code I've included below. But there are also some other issues: You could just display the layer directly, filtering the state you want to see with a SQL definition expression (see the code below). But if you don't want to for some reason… You are adding an AGSGraphic to the AGSMapView.graphicsOverlays collection. This expects an AGSGraphicsOverlay. See https://developers.arcgis.com/ios/swift/sample-code/add-graphics-with-symbols/ and https://developers.arcgis.com/ios/swift/sample-code/add-graphics-with-renderer/ fromJSON expects a geometry JSON in Esri JSON format. You are passing in featureset JSON in GeoJSON format. See this page for some more info. Your code could be using AGSRequestOperation which will take care of services that require authentication. Here are two options to display this state. One uses an AGSFeatureLayer and filters the contents with a where clause. The other does an explicit query to get a feature and create an AGSGraphic from it. Either way, you will need to add an API Key from your developer account to load the basemaps in this code… // Copyright 2022 Esri. // // Licensed under the Apache License, Version 2.0 (the "License"); // you may not use this file except in compliance with the License. // You may obtain a copy of the License at // // http://www.apache.org/licenses/LICENSE-2.0 // // Unless required by applicable law or agreed to in writing, software // distributed under the License is distributed on an "AS IS" BASIS, // WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. // See the License for the specific language governing permissions and // limitations under the License. import UIKit import ArcGIS class ViewController: UIViewController { @IBOutlet weak var mapView: AGSMapView! { didSet { mapView.graphicsOverlays.add(overlay) } } let overlay = AGSGraphicsOverlay() // Create a service feature table "linked" to the States 500K Layer let featureTable = AGSServiceFeatureTable(url: URL(string: "https://tigerweb.geo.census.gov/arcgis/rest/services/Generalized_TAB2020/State_County/MapServer/7")!) override func viewDidLoad() { super.viewDidLoad() // Visit https://developers.arcgis.com/dashboard/ to create your API key (used for basemaps) AGSArcGISRuntimeEnvironment.apiKey = "<YOUR API KEY>" let map = AGSMap(basemapStyle: .arcGISNavigation) mapView.map = map displayLayerDirectly() // queryFeaturesAndAddAsGraphics() } func displayLayerDirectly() { guard let map = mapView.map else { return } // Use a feature layer object pointing at the service feature table let layer = AGSFeatureLayer(featureTable: featureTable) // The layer by default doesn't display beyond 1:4,999,999 // See https://tigerweb.geo.census.gov/arcgis/rest/services/Generalized_TAB2020/State_County/MapServer/7 layer.minScale = 0 // Explicitly define the renderer layer.renderer = AGSSimpleRenderer(symbol: AGSSimpleFillSymbol(style: .solid, color: .orange, outline: AGSSimpleLineSymbol(style: .solid, color: .blue, width: 2.0))) // And now limit the results returned from the layer to just Idaho layer.definitionExpression = "STATE='16'" map.operationalLayers.add(layer) } func queryFeaturesAndAddAsGraphics() { // We will query against the service feature table to get the state feature we want… let queryParams = AGSQueryParameters() queryParams.whereClause = "STATE='16'" // Perform the query (no need to make data tasks explicitly, and we'll help with authentication if need be) featureTable.queryFeatures(with: queryParams, queryFeatureFields: .loadAll) { [weak self] result, error in guard let self = self else { return } if let error = error { print("Error performing query: \(error.localizedDescription)") return } guard let feature = result?.featureEnumerator().nextObject() else { return } // The polygon is already created as the feature's geometry. let polygon = feature.geometry // Create a graphic from the feature. let graphic = AGSGraphic( geometry: polygon, symbol: AGSSimpleFillSymbol( style: .solid, color: .orange, outline: AGSSimpleLineSymbol(style: .solid, color: .blue, width: 2.0)), attributes: feature.attributes as? [String : Any]) // Add the graphic to the overlay we already added to the map view. self.overlay.graphics.add(graphic) } } } Hope that helps.

Hi. Thanks for pointing that out. The row for Mobile geodatabase is slightly incorrect/misleading and we'll get the documentation updated. A Lite license will allow viewing of mobile geodatabases. A Basic license is required for editing. Editing data requires a Basic license except if the data is unsecured and shared publicly, in which case editing is supported with a Lite license (for a mobile geodatabase, that means it must be downloaded from an unsecured feature service).

From an initial look, could you turn off the spotSoundings and let us know if that helps? They seem to be slowing things down (we'll have to look into why). Once they're off, does panning/zooming behave any differently? You should be able to get to that through the shared AGSENCEnvironmentSettings… AGSENCEnvironmentSettings.shared().displaySettings.viewingGroupSettings.spotSoundings = false

Hmmm. We've taken a look and PNW does seem abnormally slow. We'll have to take a look. Thanks for reporting that.

Take a look at the sample app. You can download it form the App Store and explore capabilities. Each sample shows the code behind directly in the app, but it's also available on GitHub. But if you're looking to track the current centerpoint of the map display, you can use AGSMapView.viewpointChangedHandler. You would then want to call AGSMapView.currentViewpointWithType() and pass in .centerAndScale as the type. You'll get an AGSViewpoint back, and look at the targetGeometry. It'll be an AGSPoint that's the center of the map (you'll have to cast to AGSPoint). The point's coordinates will be in the spatial reference of the map (in this case Web Mercator) which is probably not what you want to output. You'd need to project it to WGS84. We also have a AGSCoordinateFormatter class that can help. See this code for an example: mapView.viewpointChangedHandler = { [weak self] in guard let self = self else { return } if let center = self.mapView.currentViewpoint(with: .centerAndScale)?.targetGeometry as? AGSPoint { // Format the Lat Lon etc. using a standard format if let latLonString = AGSCoordinateFormatter.latitudeLongitudeString(from: center, format: .degreesMinutesSeconds, decimalPlaces: 1) { print(latLonString) } // Get the coordinates manually… if let wgs84center = AGSGeometryEngine.projectGeometry(center, to: .wgs84()) as? AGSPoint { print("Lat \(wgs84center.y), Lon \(wgs84center.x)") } } } That will output something like this to the Xcode console… 19 56 53.8N 100 32 17.0W Lat 19.948264571145458, Lon -100.53804579499798 19 58 51.9N 100 42 37.8W Lat 19.98109671769453, Lon -100.71050437417519 20 00 03.9N 100 48 55.8W Lat 20.001080434190495, Lon -100.81549113806531 20 00 25.0N 100 50 46.6W Lat 20.006942571870393, Lon -100.84629108361138 20 00 25.0N 100 50 46.7W Lat 20.006942719211626, Lon -100.84629185776355 Please note that ENC layers require a Runtime Standard License when you're ready to deploy your app.

Hi @neddyseagoon, It's hard to tell for sure without seeing your data but it's possible that you're doing everything right and the data is just configured not to be visible outside of specific scale ranges? Are you able to share the data with us? Feel free to DM me if so and we can figure out the best way to get it to us.

Hi. The sample loads our global ocean bathymetry basemap for context and displays the ENC chart on top of it, hence the network connection. That basemap is not necessary and the ArcGIS Runtime can work entirely offline, as you need. You could try changing line 22 in the sample to: mapView.map = AGSMap(spatialReference: .webMercator()) Hope that helps!

iOS 15.4 and 15.4.1 introduced a crash in 3D applications built with the ArcGIS Runtime SDK for iOS and ArcGIS Runtime SDK for .NET (Xamarin.iOS / Xamarin.Forms-iOS) which the team have resolved with the 100.13.2 release for those SDKs. See the release notes for iOS and .NET. If your application meets the following criteria, we recommend you release an updated version of your app built with this new 100.13.2 release: Your app uses the ArcGIS Runtime SDK for iOS or the ArcGIS Runtime SDK for .NET. Your app uses version 100.13 or 100.13.1 of the ArcGIS Runtime SDK in question. Your app uses a 3D scene view (2D map views are not impacted). To learn more, including which devices are impacted, please see this blog post. This issue was logged as BUG-000148092 "Navigating a scene view crashes or freezes on newer iOS devices running iOS 15.4.".

Have you tried DisplayFilters? The Definition Expression determines what's obtained from the data source, so if you change that it will make a new request (hence the delay). Display Filters just work with the data in hand. Sounds like you want to use a ManualDisplayFilterDefinition.

Hi. The Runtime SDKs were built from the outset with performance in mind and should be able to handle 10s of thousands of pins with ease. I don't know how you're approaching this to hit that memory spike, but one approach which should certainly work is to set up an AGSGraphicsOverlay on your AGSMapView (add it to the graphicsOverlays collection), and add 1000 AGSGraphics to the AGSGraphicsOverlay's graphics collection. Each AGSGraphic can have its own symbol, but the most efficient way to handle this is to set up a renderer on the AGSGraphicsOverlay, which can efficiently share symbols between graphics in the overlay. If all your points will be displayed the same way, an AGSSimpleRenderer is suitable. Otherwise, if points should be displayed based off an attribute, use an AGSUniqueValueRenderer and populate the attributes dictionary on each AGSGraphic. These samples may help: https://developers.arcgis.com/ios/swift/sample-code/add-graphics-with-renderer/ https://developers.arcgis.com/ios/swift/sample-code/unique-value-renderer/ https://developers.arcgis.com/ios/swift/sample-code/simple-renderer/ https://developers.arcgis.com/ios/swift/sample-code/picture-marker-symbols/ One other thought: if you are using images for your symbols with an AGSPictureMarkerSymbol, be sure the image is a sensible size. You don't need a 10MB image just to display a point on a map. Consider scaling it appropriately. Hope that helps.

FYI: Here is a blog post about this crash. I will accept it as the solution so it appears up front to anyone reading this post.
