I believe that not all areas of the world have tiles to the highest LOD level. That is probably what you're encountering here. One option you could consider is exporting the vector tile version of the basemap. See here. Can you check the output of estimateExportTileSize to know that the call to export will fail? Update: Note that there are also For Export versions of the Vector Tile layers which have a smaller set of fonts. Exporting those is about 70MB smaller than the default Vector Tile layers, but may not have all the fonts you need for non-English labels. The World Streets raster basemap does not include tiles for levels 20-23. The LODs are defined so that the layer can be used in maps that resample lower resolution tiles without limiting the zoom level of the map. The world imagery service *does* include tiles up to LOD level 23. ... View more

A couple of notes. The openstreetmap basemap that Runtime provides a shortcut for pulls tiles from openstreetmap.org, so William Craft‌'s response above is correct: add *.openstreetmap.org to the whitelist. You can find this out by turning on URL logging in the Runtime and checking the console output in Xcode. You can turn on global debugging with this code (though don't put this in production code as it affects performance): AGSRequestConfiguration.global().debugLogRequests = true‍‍‍‍ From that I could see that you'd need to whitelist openstreetmap.org. 2020-02-21 12:20:23.475207-0500 TestOSM[30781:5832027] **------>> sending request** - [https://a.tile.openstreetmap.org/0/0/0.png](https://a.tile.openstreetmap.org/0/0/0.png) - GET ----- 2020-02-21 12:20:23.608706-0500 TestOSM[30781:5832024] **------>> sending request** - [https://b.tile.openstreetmap.org/1/0/0.png](https://b.tile.openstreetmap.org/1/0/0.png) - GET -----‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ There is a Vector Tile version of the OpenStreetMap basemap which Esri hosts now, and for which a whitelist entry of basemaps.arcgis.com or *.arcgis.com would be suitable. You can find that here. It is not currently part of the Runtime's shortcut enumerations when defining an AGSMap, but you can make use of it like this: let osmItem = AGSPortalItem(portal: .arcGISOnline(withLoginRequired: false), itemID: "3e1a00aeae81496587988075fe529f71") let osmVectorLayer = AGSArcGISVectorTiledLayer(item: osmItem) let map = AGSMap(basemap: AGSBasemap(baseLayer: osmVectorLayer))‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ Hope this helps! ...

Reading your response I was going to suggest Group Layers (or else using Feature Collection Layers as your placeholders). I think Group Layer is your friend here. Note also the new AGSSubtypeFeatureLayer that was released with 100.7. That's very helpful where you have a single feature service layer with multiple subtypes that you want to treat separately. It's conceptually like an automated group layer: It'll give you a sub-layer per subtype, but is smart about how it queries back to the server when it needs to get data for those sub-layers. ...

Can you explain a little more how you're using it this way that makes it useful for you? Not sure I follow. Thanks! Nick. ... View more

We don't have a way to lean on UIKit system colors (one of the side-effects of having a cross-platform core to the Runtime). While you should be able to manually modify the labels, we don't have an API for this yet. But if you're willing to tinker with some JSON you should be able to get this to work. On an AGSFeatureLayer there is a labelDefinitions property. This is an array of AGSLabelDefinition objects. You could call toJSON on each AGSLabelDefinition in that array, modify the appropriate symbol color and then create a new AGSLabelDefinition from the modified JSON using AGSLabelDefinition.fromJSON, and replace the definition in the labelDefinitions array. It's messy but should work. We're working on fleshing out these APIs in future releases, but for now ask that you get the JSON and work with that. Let me know if that helps. Nick ... View more

Hi Cory, As Mary and Joe pointed out, you shouldn't have to call downloadGeodatabaseForLayers and you shouldn't set returnSchemaOnlyForEditableLayer to true (that's why you're not getting any data). There's a more fundamental issue which is, I think, why you might be seeing an error. You are not holding on to the OfflineMapTask, nor the Job. Not entirely sure why that would give you the error you're seeing but I suspect something is bubbling up internally and being caught by code that expects something specific. Anyway, if you provide a class level var to hold the AGSOfflineMapTask and the AGSGenerateOfflineMapJob (see lines 34 and 35 below), and you remove the line that sets returnSchemaForEditableLayers, your code works: import UIKit import ArcGIS class ViewController: UIViewController { @IBOutlet weak var mapView: AGSMapView! override func viewDidLoad() { super.viewDidLoad() // Do any additional setup after loading the view. mapView.map = AGSMap(url: URL(string: "https://geeknixta.maps.arcgis.com/home/item.html?id=8e88bb4d6cc048cbb61686fbfb26a0b9")!) mapView.touchDelegate = self } var offlineMapTask: AGSOfflineMapTask! var offlineMapJob: AGSGenerateOfflineMapJob! func takeMapOffline(areaOfInterest: AGSGeometry) { //1. Declare offline map task //let offlineMapTask = AGSOfflineMapTask(onlineMap: self.mapView.map!) guard let onlineMap = mapView.map else { return } // IMPORTANT: hold on to the Task while it executes offlineMapTask = AGSOfflineMapTask(onlineMap: onlineMap) //2. Define parameters offlineMapTask.defaultGenerateOfflineMapParameters(withAreaOfInterest: areaOfInterest, completion: { [weak self] (parameters, error) in // IMPORTANT: If we hadn't held on to the task above, this is at risk of not executing. // However, because offlineMapTask was referenced below when creating the job, // Swift would have kept it around, but it's better practice to keep hold of it just in case. print("@@@ Generate parameters 1: Start") if let error = error { print("@@@ Generate parameters 2b: Error, getting parameters failed") print(error) self?.showDownloadFailedAlert("Error generating offline parameters: \(error.localizedDescription)") return } guard parameters != nil else { print("takeMapOffline: No parameters provided") return } guard let self = self else { return } if let parameters = parameters { parameters.maxScale = 3600 parameters.minScale = 30000 parameters.includeBasemap = true parameters.isDefinitionExpressionFilterEnabled = true parameters.continueOnErrors = true // parameters.returnSchemaOnlyForEditableLayers = true parameters.attachmentSyncDirection = .bidirectional parameters.returnLayerAttachmentOption = .allLayers print("@@@ Generate parameters 2a: Got parameters!") //4. Create the job print("@@@ Generate parameters 3: create job") let mapStorageURL = self.getNewOfflineMapDirectoryURL() UserDefaults.standard.set(mapStorageURL, forKey: "OfflineMapDirectoryUrl") // IMPORTANT: Hold on to the Job while it executes. This is where the original code was // exposing itself to not completing properly. self.offlineMapJob = self.offlineMapTask.generateOfflineMapJob(with: parameters, downloadDirectory: mapStorageURL) //5. Run the job self.startOfflineMapJob(job: self.offlineMapJob, areaOfInterest: areaOfInterest) } }) } var downloadProgressObserver: NSKeyValueObservation? func startOfflineMapJob(job: AGSGenerateOfflineMapJob, areaOfInterest: AGSGeometry) { downloadProgressObserver = job.progress.observe(\.fractionCompleted, changeHandler: { (progress, _) in DispatchQueue.main.async { print("Progress at \(progress.fractionCompleted * 100)%") } }) print("Job Started: Downloading map selection.

Hi. Are you asking for a programatic way to import the geometry JSON into ArcGIS Pro, or for a tool in ArcGIS Pro to read the geometry JSON? If the former, I think this question belongs in the ArcGIS Pro SDK place. Programatically, perhaps start here. It also looks like there's a JSON Import tool in ArcGIS Pro. See here. But note that geometry.tojson() will only output the JSON for the geometry object, not a full feature. The ArcGIS Pro links above require full Featureset JSON - see here. You may need to process your geometry JSON into that format to import it. ... View more
