Release notes for 200.2

Filter features in 3D object and point scene layers

Scene layers of type 3D object or point scene layer now support filtering by features and by area. Support includes web scenes published containing scene layers with filtered features. Features can be filtered using one of the following new methods on the ArcGISSceneLayer class:

• setVisible() - Sets the visibility of a single feature in the scene layer.
• setVisible<S>() - Sets the visibility of multiple features in the scene layer.
• resetFeaturesVisible() - Resets the visibility of all features in the scene layer.

Features in scene layers can also be filtered spatially using one or more polygon areas. A new class called SceneLayerPolygonFilter defines a filter from a set of polygons and a spatial relationship. The spatial relationship determines whether to show only those features inside the filter area or those outside the specified area. The filter is applied to the ArcGISSceneLayer via a new polygonFilter property.

Support for relative to ground surface placement mode

Scene layers of type 3D object scene layer or point scene layer now support features with a surface placement mode value of Relative (relative to the ground surface). This enhancement adds initial support for a new collection of global 3D scene layers. With this release, the Living Atlas layer OpenStreetMap 3D Buildings (Beta) can now be used in your 3D scenes.

Edge rendering

This release completes support for displaying edges on 3D object scene layers across all Native Maps SDKs and on all platforms.

Support for custom feeds

With this release of ArcGIS Maps SDKs for Native Apps, you can create a custom DynamicEntityDataSource. This new API allows you to bring data from custom feeds that you manage into a DynamicEntityDataSource as dynamic entities. You can visualize them in your application using a DynamicEntityLayer. The API is flexible, allowing you to manage the connection and process data from any data feed required by your application. Use the custom DynamicEntityDataSource to connect to a variety of feed types from streaming feeds over a socket to data files that are updated over time.

Specify fields when connecting to an ArcGIS stream service

This release includes the ability to specify a subset of fields from an ArcGIS stream service using ArcGISStreamServiceFilter.outFields.

Support for camera controller, viewshed, and line of sight on a dynamic entity observation

In addition to a DynamicEntity, you can now use a DynamicEntityObservation as the input to a GeoElementViewshed, GeoElementLineOfSight, and OrbitGeoElementCameraController.

Performance improvements

Several performance improvements have been made to dynamic entities in this release. DynamicEntityObservation attribute information is now compressed down to 25% of previous sizes, and observational parsing has been increased by up to a factor of four, allowing for higher throughput.

Support for clustering of point features

With this release, ArcGIS Maps SDKs for Native Apps adds support for feature clustering. Point features in a feature layer can be clustered in a map when displayed using dynamic rendering mode.

Feature clustering dynamically aggregates groups of points that are within proximity of each other so they can be represented with a single symbol. The size of the symbol indicates the relative number of points it represents. Clusters are updated as the map scale and extent changes, allowing you to see patterns in the data that may otherwise be difficult to visualize with a large number of overlapping points. You can use ArcGIS Pro or ArcGIS Online to author and publish point feature layers enabled with clustering.

Adding a cluster-enabled feature layer to your Native Maps SDKs app, or opening a web map that contains one, will render clusters if the layer's rendering mode is dynamic. If the rendering mode is set to static, individual features in the layer are drawn using the layer's renderer.

Here are some details about working with clustering in ArcGIS Maps SDKs for Native Apps:

• A layer's renderer is separate from its cluster renderer. If a cluster renderer was not defined when authoring the data, the layer's renderer is used to infer cluster symbology.

• If the rendering mode is set to static, individual features are drawn using the layer's renderer. This is the same appearance the layer would have if clustering was not enabled.

• Point features that are not included in a cluster are drawn as individual features using the layer's renderer.

• Clusters are dynamically updated as the map's scale and extent changes.

• Identifying a clustered geoelement returns an AggregateGeoElement. The geometry of an aggregate geoelement is the centroid of the cluster graphic and its attributes are the summary fields defined at the time of authoring or publishing the layer.

• Pop-ups on clusters are separate from the pop-ups defined on a feature layer. When you identify an aggregated geoelement, you can get access to pop-ups defined on the clusters.

• You can toggle the visibility of clusters. When clusters visibility is turned off, the individual features are drawn.

• Clustering does not apply to layers with polyline and polygon geometries and is not supported in 3D.

Here are a few known issues with clustering in this release:

• Clusters do not display labels.

• Cluster graphics cannot be selected or highlighted.

• Pop-up expressions that use the $aggregatedFeature variable are not evaluated.

• If the authored cluster symbology contains size visual variables on a summary field other than cluster_count, the cluster symbols do not display with the correct sizes.

Programmatically move, rotate, and scale geometry

The GeometryEngine class introduces new static methods to move, rotate, or scale geometries.

Interactively rotate and scale geometry

The GeometryEditor now displays control graphics when appropriate geometry editor elements are selected. These graphics allow the user to interactively rotate and apply uniform or free-stretch scaling to the selected elements.

Create predefined shapes

The new ShapeTool, for use with the GeometryEditor, allows you to create a predefined shape, such as ellipse, triangle, rectangle, and arrow. These shapes can be represented using polyline or polygon geometry.

Utility Network offline tracing enhancements

Offline tracing support was added to the Native SDKs 200.1 release and has been improved in 200.2 with additional bug fixes and tracing support.

• The ArcGIS Maps SDKs for Native Apps now support tracing of utility networks taken offline from an ArcGIS Enterprise 11.1 feature service.
• Offline traces now support nearest neighbor trace results and loops tracing.
• Offline traces have an improved performance when tracing with propagators. These new tracing enhancements are available for all mobile geodatabase types.

SubtypeSublayer feature templates

Custom feature templates can be configured for each FeatureSubtype in a Subtype Group Layer using ArcGIS Pro, and the Native Maps SDKs now provide these templates via the SubtypeSublayer.featureTemplates property.

Support for Arcade 1.23

ArcGIS Maps SDKs for Native Apps now support Arcade V1.23. Enhancements include the following:

• Support for new geometry functions NearestCoordinate and NearestVertex.

• Support for binary and octal number literals.

• Updates to Feature and Dictionary functions. These functions now accept more types, easing conversions between features, dictionaries, and geometries.

• Reduction of preparation time by half when a script is evaluated. This reduction is most significant in multiple evaluations of a small script, for instance a script calculating a value from a few feature attributes.

The newly added GetEnvironment function has limited support: locale and application values always return empty strings.

Enhancements for map and scene interaction

• Navigating the map in 2D and scene in 3D is now supported with keyboard shortcuts on iPadOS and Mac Catalyst.
• New events have been added to MapView and SceneView that indicate whether the user is interactively panning, zooming, or rotating the map or scene. See onInteractiveZoomingChanged(perform:), onInteractivePanningChanged(perform:), onInteractiveRotatingChanged(perform:).
• New events have been added to MapView and SceneView to indicate whether the user is performing a drag gesture. Developers can customize the handling of this gesture, for example, to interactively move a graphic instead of panning the map. See onDragGesture(shouldBegin:onChanged:onEnded:onCancelled:).
• A magnifier is displayed on the map in response to a long-press gesture.

OAuth Application Credential

OAuth Application Credential is now supported. OAuth Application Credential uses the registered application's credentials to access secured services on ArcGIS. It manages ArcGIS authentication and grants a short-lived access token generated via OAuth 2.0 using the application's client ID and client secret outside of the context of a user.

Shortly after iOS 17 was announced during Apple's WWDC conference in June 2023, testing began on the developer and public betas to ensure apps built with ArcGIS Maps SDK for Swift could adopt it quickly. Following the official release of iOS 17 on September 18, 2023, ArcGIS Maps SDK for Swift version 200.2 was certified to support iOS 17.

• PopupAttachment.fileURL has been marked optional to reflect that it is initialized only after the PopupAttachment has been loaded.
• DynamicEntityDataSource.disconnect() has been marked non-throwing.

• Projection Engine compatibility: The internal directory structure of the Projection Engine data files has changed. The new file structure within the Projection Engine data files version 200.2 is supported with ArcGIS Maps SDKs for Native Apps version 200.1 or later. If your application deployment includes the Projection Engine data files, you may need to update your build or setup process to reflect this change.

• GeometryEditor.symmetricDifference now supports curves.
• Projection engine (PE) data for geographic transformations are arranged in a different file structure than previous releases. This change is designed to accommodate the increasing number, complexity, and size of the data files. See the readme in the projection engine data download for more information.
• LabelDefinition.whereClause sql can now include N for literal unicode text.

There are no API deprecations with this release.

There are no OS and framework deprecations with this release.
