Declaration

Discussion
The session tracks device motion, captures and processes scene imagery from the device camera, and coordinates with your delegate object or ARSCNView or ARSKView view only when running.
Calling this method on a session that has already started transitions immediately to the new session configuration. The options parameter determines how existing session state transitions to the new configuration. By default, the session resumes device position tracking from the last known state and keeps any anchors already included in the session (those you've added manually with add(anchor:), as well as those added automatically by ARKit features such as plane detection or face tracking).
This method returns immediately when called, but the session continues to run.
