New APIs and capabilities

The new ARCore Scene Semantics API is now available on iOS. Scene Semantics runs an ML model on the camera image feed and provides a semantic image with each pixel corresponding to one of 11 labels of outdoor concepts.

• GARFrame.semanticImage: Provides the semantic labelling image for the last camera image.
• GARFrame.semanticConfidenceImage: Provides the confidence values for each pixel in the semantic image.
• GARSessionConfiguration.semanticMode: Configuration option enabling semantics.
• GARSemanticLabel: Enum for semantic label classes.

Other changes

• The SDK no longer supports deployment targets < 12.0.

Bug fixes

• #139: Fixed a crash caused by creating Rooftop or Terrain Anchors outside of supported areas.

New APIs and capabilities

Streetscape Geometry

Streetscape Geometry is a new ARCore Geospatial API that provides the geometry of buildings and terrain in an area around the user when the Geospatial API is enabled.

See Streetscape Geometry Developer Guide (iOS) for more information. Additionally, the GeospatialExample app has been updated to include Streetscape Geometry.

• GARStreetscapeGeometry:
  • GARStreetscapeGeometry.mesh provides 3D meshes.
  • GARStreetscapeGeometry.meshTransform provides the origin transform of the geometry relative to the session's world space.
  • GARStreetscapeGeometry.trackingState maintains the tracking state.
  • GARStreetscapeGeometry.type indicates if it is terrain or building geometry.
  • GARStreetscapeGeometry.quality provides the quality of geometry.
  • GARStreetscapeGeometry.identifier provides the unique identifier for the geometry.
• GARSession.createAnchorOnStreetscapeGeometry:transform:error: creates an anchor at the specified location and orientation.
• GARSession.raycastStreetscapeGeometry:direction:error: performs a raycast against Streetscape Geometry loaded in the scene.

Rooftop anchors

Rooftop anchors are a new Geospatial anchor type that helps you anchor content to a rooftop.

See Geospatial anchors (iOS) for more information. Additionally, the GeospatialExample app has been updated to include Rooftop anchors.

• GARSession.createAnchorWithCoordinate:altitudeAboveRooftop:eastUpSouthQAnchor:completionHandler:error: creates a Rooftop anchor at the specified location, altitude above the rooftop in meters and orientation relative to the Earth.
• GARCreateAnchorOnRooftopFuture holds the asynchronous state of resolving a Rooftop anchor.
• GARRooftopAnchorState describes the state of resolving a Rooftop anchor.

ARCore async APIs

This release introduces new ARCore async APIs to improve ergonomics when working with asynchronous operations, following the Future paradigm.

• Resolving Terrain anchors: Use GARSession.createAnchorWithCoordinate:altitudeAboveTerrain:eastUpSouthQAnchor:completionHandler:error: to obtain a GARCreateAnchorOnTerrainFuture. The old symbol GARSession.createAnchorWithCoordinate:altitudeAboveTerrain:eastUpSouthQAnchor:error: has been deprecated and may be removed in a later version of ARCore.
• Resolving Cloud anchors: Use GARSession.resolveCloudAnchorWithIdentifier:completionHandler:error: to obtain a GARResolveCloudAnchorFuture. The old symbol GARSession.resolveCloudAnchorWithIdentifier:error: has been deprecated and may be removed in a later version of ARCore.
• Hosting Cloud anchors: Use GARSession.hostCloudAnchor:TTLDays:completionHandler:error: to obtain a GARHostCloudAnchorFuture. The old symbols GARSession.hostCloudAnchor:error: and GARSession.hostCloudAnchor:TTLDays:error: have been deprecated and may be removed in a later version of ARCore.

Deprecations

• With the addition of asynchronous Cloud Anchor and Terrain Anchor methods, the following are now obsolete and deprecated:
  • GARAnchor(Geospatial)
  • GARAnchor.terrainState
  • GARTerrainAnchorStateTaskInProgress
  • GARAnchor(CloudAnchors)
  • GARAnchor.cloudIdentifier
  • GARAnchor.cloudState
  • GARCloudAnchorStateTaskInProgress
  • GARSession.hostCloudAnchor:error:
  • GARSession.hostCloudAnchor:TTLDays:error:
  • GARSession.resolveCloudAnchorWithIdentifier:error:
  • GARSessionDelegate
  • GARSessionDelegate.session:didFailToHostAnchor:
  • GARSessionDelegate.session:didHostAnchor:
  • GARSessionDelegate.session:didFailToResolveAnchor:
  • GARSessionDelegate.session:didResolveAnchor:
  • GARSession.delegate
  • GARSession.delegateQueue
  • GARSession.createAnchorWithCoordinate:altitudeAboveTerrain:eastUpSouthQAnchor:error:

Other changes

• GARFuture is a new base type for async operations with property GARFuture.state and method GARFuture.cancel. GARVPSAvailabilityFuture now extends GARFuture.

Other Changes

• The ARCore iOS SDK now officially supports Swift Package Manager. See Enable AR in your iOS app for instructions on how to integrate with ARCore using Swift Package Manager.
• Adds copyright statements added to files that were inadvertently missing them previously.

Bug fixes

• Various bug fixes and performance improvements.

New APIs and capabilities

• All Geospatial transforms now expose their orientation accuracy of the Yaw rotation, replacing heading accuracy.
• GARGeospatialTransform.orientationYawAccuracy

Deprecations

• GARGeospatialTransform.heading has been deprecated. Please use GARGeospatialTransform.eastUpSouthQTarget instead.
• GARGeospatialTransform.headingAccuracy has been deprecated. Please use GARGeospatialTransform.orientationYawAccuracy instead.

Other changes

• ARCore Geospatial API checkVPSAvailabilityAtCoordinate:completionHandler will continue to retry silently in the background if it is unable to establish a connection to the ARCore service for 5 seconds.
