## Overview

The `AVMetadataFaceObject` class is a concrete subclass of [`AVMetadataObject`](/documentation/AVFoundation/AVMetadataObject) that defines the features of a single detected face. You can retrieve instances of this class from the output of an [`AVCaptureMetadataOutput`](/documentation/AVFoundation/AVCaptureMetadataOutput) object on devices that support face detection.

A Boolean value indicating whether there is a valid roll angle associated with the face.

[`rollAngle`](/documentation/AVFoundation/AVMetadataFaceObject/rollAngle)

The roll angle of the face specified in degrees.

[`hasYawAngle`](/documentation/AVFoundation/AVMetadataFaceObject/hasYawAngle)

A Boolean value indicating whether there is a valid yaw angle associated with the face.

[`yawAngle`](/documentation/AVFoundation/AVMetadataFaceObject/yawAngle)
