Starts AR processing for the session with the specified configuration.
- iOS 11.0+
An object that defines motion and scene tracking behaviors for the session.
Calling this method on a session that has already started transitions immediately to the new session configuration. After you call this method, the session runs asynchronously.
To determine how existing session state transitions to the new configuration, use the
run method instead. Calling
run is equivalent to calling
run with no options enabled.
