worldMappingStatus
The feasibility of generating or relocalizing a world map for this frame.
Declaration
var worldMappingStatus: ARFrame.WorldMappingStatus { get }Discussion
Every world-tracking session builds an internal world map, which ARKit uses to determine the device’s position in the user’s environment. You can save a snapshot of that internal state as an ARWorldMap object, which you can use later to resume the saved session or share between devices to create a multiuser AR experience.
While you can call getCurrentWorldMap(completionHandler:) at any time during a session, some times are better than others. Use this property to determine whether the session currently has enough data to generate a useful ARWorldMap or if it’s better to wait for the session to map more of the user’s local environment first.
