# isWorldTrackingEnabled

A Boolean value that instructs a session to provide the app with the device’s six degrees of freedom pose during a face-tracking session.

```
var isWorldTrackingEnabled: Bool { get set }
```

## Discussion

Before attempting to enable this property, check whether the iOS device supports user-face tracking in a world-tracking session, by calling [`supportsWorldTracking`](/documentation/ARKit/ARFaceTrackingConfiguration/supportsWorldTracking).
