Thank you, Nimesh With those inputs I'm able to achieve exactly what I need by following such steps: disableAutoSyncToKeychain() removeAllCredentials() portal.credential = nil At least for my use case, it's not necessary to setting AGSPortal to nil. Now setting portal credentials to nil works, because in addition I've removed credentials from cache(missing step from my first approach)

Multiple user accounts implementation · ‎05-18-2020

Hi, Let's assume the application need to store multiple user accounts and to be able to switch between them without re-login. Just like in any Mail app, etc. What is the best approach for achieving this? To be specific: users should be logged in using OAuth mechanism via Authentication Manager (AGSAuthenticationManager). In order to store and use multiple users credentials in the keychain, I'm using enableAutoSyncToKeychain(withIdentifier: , accessGroup:, acrossDevices:) method call with unique keychain identifier for each user. It works fine but with limitations to switch between stored user credentials. While switching between accounts, calling AGSAuthenticationManager.shared().credentialCache.disableAutoSyncToKeychain() and than AGSAuthenticationManager.shared().credentialCache.enableAutoSyncToKeychain() with a keychain identifier for new user doesn't perform the trick and mess things up. Also, setting the portal.credential to nil doesn't help. The application still have access to the user specific data. Looks like credentials in some way cached in the RAM. So the only way to actually switch between stored user credentials I've found so far, is to recreate the AGSPortal object from scratch and to call .enableAutoSyncToKeychain() with new identifier after. To summarise: is it possible to switch between user/credentials_in_keychain without recreating AGSPortal object? Or what is the suggested way of achieving work with multiple accounts using SDK? Thanks.

Thank you, I was briefly looking at AGSSketchEditor.style property at first without success. It turns out I should look for feedbackFillSymbol and feedbackFillSymbol properties to achieve my needs.

Thank you, that is exactly I'm looking for. CPU performance is pretty the same, but there is helpful addition like undo manager. The only concern is how to tweak color/style of the geometries? For example while creating graphics manually, I'm able to tweak AGSSimpleFillSymbol style, color and outline.

Currently I'm leveraging on AGSGeoViewTouchDelegate. Specifically on didTouchDownAtScreenPoint and other methods in order to manually draw geometry on the map. Since there are a lot of map points received by delegate method, they are normalised to rectangle instead of polygon. Also worse to mention, in order to draw the user's choice rectangle in real time, AGSGraphics object is repeatedly deleting and adding from AGSGraphicsOverlay object during the each didTouchDragToScreenPoint method call like so: graphicsOverlay.graphics.removeAllObjects() graphicsOverlay.graphics.add(polygonGraphic)‍‍ ...where polygonGraphic is normalised rectangle (4 AGSPoint objects) It works, but my concern is about CPU usage. During creating selection rectangle on the map, CPU usage can be up to 30% for my current iOS device. It's not that big in comparison if the user scales or moving area of the map that will use 80+% of CPU.

There is need to be able to draw a polygon/rectangle on the map in order to select intersecting features with that drawing. I can see from the Feature Layer Selection Runtime SDK for .NET example: The sample uses the MapView.RequestShapeAsync method to allow the user to draw a selection rectangle intersecting features that he would like to manage.Once the selection rectangle is returned, a SpatialQueryFilter is used to spatially select features in the feature layer using FeatureLayer. Specifically var rect = await MyMapView.Editor.RequestShapeAsync(DrawShape.Rectangle);‍ I can't find any similar Editor of the MapView for the iOS version of the SDK. Feature Layer Selection Runtime SDK for iOS example only provides the solution how to select feature by tap point but not by drawing graphics area. I want to achieve basic functionality as this dashboard provides. User can select features not only by point but also by rectangle, lasso, circle and line. Is there any solution or starting point for this? example of selected features by rectangle selection

same screen. Current application displays only one map view, but creates and loads few map objects. Isn't that an anti-pattern for the Runtime SDK and AGSMap instance should be globally visible singleton object instead? P.S. Following my guess. Looks like trick with the singleton map object did the job for me. Crash is absent so far.

From time to time I'm encountering crash during launching the application. Runtime SDK version 100.6 Thread 8: EXC_BAD_ACCESS (code=1, address=0x0) Thread 8 Queue : com.esri.arcgis.requestOperation.data (serial) #0 0x000000010a72e08e in void std::__1::__tree_balance_after_insert<std::__1::__tree_node_base<void*>*>(std::__1::__tree_node_base<void*>*, std::__1::__tree_node_base<void*>*) () I've tried to execute po (SEL)$arg2 but the result is <no value available> (SEL)$arg3 -> " \xffffffd2\xffffff91" (SEL)$arg5 -> "\x01/attriba" Can someone take a look for the Runtime SDK source code in order to examine which methods are using the "com.esri.arcgis.requestOperation.data" serial queue? It might help to understand where the problem is.

Thanks, Nicholas, with your guidance I’m happy to know I was looking into correct direction for solution and feel full confidence now. Once I’ll get full info regarding exact features which are intended to use with App Login within App, possibly I’ll contact directly to discuss if need. In addition, while playing with all this auth functionality discussed on Github, I’ve faced with strange behavior of not getting any callback for Portal load method under specific circumstances. Once everything is double checked I’ll provide description of this possible issue. Thanks for help and detailed explanations!

There is a way to authenticate on behalf of User using App Login Rest API Implementing App Login | ArcGIS for Developers but is it available for using with Runtime SDK? Documentation suggest to use AGSAuthenticationManager class for that: “ Client credentials: registration requires a client ID, client secret, and a redirect URL. The user does not need to enter a login, but rather is granted access on behalf of the app.” ... but there is no any way to provide client secret for the AGSAuthentication manager class methods either in Documentation or header files of ObjC library. So the question is how to implement App Login using native iOS SDK instead of using Rest API?

Thank you for answer.

All the properties of AGSPortalUser are nullable. The question: is it even possible in practice to have AGSPortalUser instance with username to be null? I'm trying to relay on this property as a unique identifier of the user and want to be sure if I can force unwrap it with Swift safely.

‎09-24-2019

I'm wondering if it's possible to achieve App Login using latest at the moment ArcGIS Runtime SDK for iOS v.100.6 after 5 years the initial question raises.
