userFaceTrackingEnabled
A flag that determines whether ARKit tracks the user’s face in a world-tracking session.
Declaration
var userFaceTrackingEnabled: Bool { get set }Discussion
When enabled, ARKit provides you with an ARFaceAnchor that represents the user’s face during your world tracking session. For example, you can share avatar expressions with multiple users in a multiplayer game, or enable the player to control a virtual object in the physical environment using facial expressions.
Check whether the device supports tracking of the user’s face by using supportsUserFaceTracking before enabling this property.
