## Discussion

When the [`worldMappingStatus`](/documentation/ARKit/ARFrame/worldMappingStatus-swift.property) of the session’s [`currentFrame`](/documentation/ARKit/ARSession/currentFrame) is [`ARFrame.WorldMappingStatus.notAvailable`](/documentation/ARKit/ARFrame/WorldMappingStatus-swift.enum/notAvailable), the session has no internal map of the real-world space around the device, nor the scene visible to the camera. Calling [`getCurrentWorldMap(completionHandler:)`](/documentation/ARKit/ARSession/getCurrentWorldMap(completionHandler:)) at this time results in an error.

This status occurs shortly after starting a new session. To save or share a world map, wait for the user to explore their surroundings and the session’s status to change to [`ARFrame.WorldMappingStatus.mapped`](/documentation/ARKit/ARFrame/WorldMappingStatus-swift.enum/mapped) or [`ARFrame.WorldMappingStatus.extending`](/documentation/ARKit/ARFrame/WorldMappingStatus-swift.enum/extending).
