Hi Ken. Update 3 is slated for this year, yes. At present I'm afraid there is no such list, but perhaps you can post an idea about a Runtime Roadmap here and set the category as ArcGIS Runtime? Cheers, Nick ... View more

Hi Ken. We don't currently support Vector Tile layers in Scenes. Draping them in a scene is on the roadmap, currently slated for Update 3 although that could change. Nick. ... View more

No problem Trevor. The AGSPortalItem is very generic (it could be a map, or a CSV file, or even an Excel spreadsheet) so it doesn't expose type-specific info (think of it as a Content Management System item where ArcGIS Online or your own portal is the CMS but with geo-capabilities). The "type" property will tell you what it represents. In your case you happen to know it's a FeatureService, which is great. To find out what the sublayers are, it's a bit opaque but can be done. Take the Feature Service URL (that should be accessible via portalItem.serviceURL if the portal item has loaded) and instantiate yourself an instance of AGSGeodatabaseSyncTask. Then call loadWithCompletion() on it. In the completion handler, you'll be able to read the featureServiceInfo property, which gives rich information about the FeatureService itself. Probably more than you wanted to learn about I feel we could expose this a little better, but it's low priority as AGSGeodatabaseSyncTask is very lightweight, does the job, and most use-cases don't need it. Let me know how that goes. ... View more

Sorry. I misread. Entirely my fault. You want to use an AGSArcGISMapImageLayer for a MapService endpoint. Forget the "/0" on the end, instead of the AGSFeatureServiceTable and AGSFeatureLayer, simply instantiate an AGSArcGISMapImageLayer. See this sample. That'll add the layer to the map. Nick. P.S. If you need access to the individual features and attributes, the layer's publisher will need to enable that (if it isn't already) and then there'll be a FeatureService sibling to the MapService which you can access as per my answer from yesterday. ...

Your URL is pointing at the service, but you should specify an individual layer URL within that service. So perhaps add "/0" to the end of the URL to make "https://arcgis.../MapServer/0" (if there are multiple layers, use the right layer index). Let me know if that's the issue. You could also call loadWithCompletion() on featureTable and check for any error in the completion block. That could give you some indication of what's going wrong. Nick. ... View more

Great stuff. Good to hear. Would you mind marking some answers as Helpful etc.? Nothing like that Esri Community Karma   Thanks! Nick. ... View more

I'm betting that code is within a func. That func is being exited before the async call returns, and so "table" is being deallocated before the service responds and the block isn't being called. Try making the "table" variable a class variable instead. So something like this. class ViewController: NSViewController {     ...     // Declare "table" here as a class-level variable     // table will not be deallocated just because queryTable() finished.     var table:AGSServiceFeatureTable!         func queryTable() {         // Here we set the class level variable rather than declaring         // a local variable that is deallocated when the function exits.         table = AGSServiceFeatureTable(item: portalItem, layerID: 0)                 let params = AGSQueryParameters()         params.whereClause = "1=1"                 // Fire off the query asynchronously... But...         table.queryFeatures(with: params, completion: { (results, error) in             guard error == nil else {                 print("Error querying... \(error!.localizedDescription)")                 return             }             print("Got a result")         })         // ...the code will exit this function before the query returns.     }     ... }‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ Note that this isn't going to happen if you're reading from, say, a layer on a map in a mapview with something like (pseudocode alert) mapview.map.operationalLayers[0].featureTable because the map and layer will still be "alive" so you'll be querying against a table that isn't going to be deallocated (it's referenced by the layer which is referenced by the map which is referenced by the mapview which is referenced by the app's UI). In this case what you're seeing is because you're declaring a standalone table item that Swift will deallocate just like any other variable declared in that block. ... View more

Aha. Ok, so that property refers to what's cached locally in the feature table. You would need to set the table's featureRequestMode to Manual for that and call populateFromServiceWithParameters. But that's more advanced than you need… Instead, just call one of the query functions. If you need to know the total record count in the service, use a queryParameter with whereClause of 1=1 and call queryFeatureCountWithParameters to get the result. That's an async operation by necessity.

Hi Trevor. That's Xcode being a pain. I'm sure if you just type the constructor like this it'll compile: let table = AGSServiceFeatureTable(item: portalItem, layerID: 0)‍ let layer = AGSFeatureLayer(featureTable: table) ‍‍‍‍‍‍‍‍ One thought - can you scroll up in that autocomplete list? Perhaps Xcode is scrolling you to the second suggestion for some reason (I think I've seen that before). Alternatively, if you have other errors in the code, Xcode can get confused with what it offers for autocomplete. Xcode gets better at this with each release, in case you're not on the latest.

Indeed. I've pointed the .NET team at your question. I did overhear something about whitelisting using the project manifest/settings but since it's way out of my wheelhouse I'll wait for them to pipe up. That might give you something to look into in the meantime though. ... View more

FYI: In Runtime 100, the iOS SDK moved the trustedHosts property to the AGSAuthenticationManager. But we'll get this moved over for the .NET/Xamarin folks to chip in. ... View more

Take a look at the search parameters here. You should be able to use either the access property or the orgid term to build an AGSPortalQueryParameters using queryParametersWithQuery() to pass to the portal.findItems() call. If you use orgid, you can get it from portal.portalInfo.organizationID. Also, since this could return a lot of items, consider paging through the results. Let me know how that goes! ... View more

Thanks for that. This is an issue that we've fixed in version 100. However, that doesn't really help you with version 10.2.5. Are you considering updating to the current Runtime SDK (version 100.x)? ... View more
