Properties

cloudIdentifier

@property(nonatomic, readonly, nullable) NSString *cloudIdentifier;

Cloud Anchor identifier, if applicable.

This will be nil unless the cloud state of the anchor is GARCloudAnchorStateSuccess.

Provided by category GARAnchor(CloudAnchors).

identifier

@property(nonatomic, readonly) NSUUID *identifier;

The Terrain anchor state, if applicable.

Indicates the state of the resolving operation on this anchor, if any.

Provided by category GARAnchor(Geospatial).

trackingState

@property(nonatomic, readonly) GARTrackingState trackingState;
