# supportsUserFaceTracking

A Boolean value that tells you whether the iOS device supports tracking the user’s face during a world-tracking session.

```
class var supportsUserFaceTracking: Bool { get }
```

## Discussion

Check the value of this property first, before you enable face tracking using [`userFaceTrackingEnabled`](/documentation/ARKit/ARWorldTrackingConfiguration/userFaceTrackingEnabled).
