# ARParticipantAnchor

An anchor for another user in multiuser augmented reality experiences.

```
class ARParticipantAnchor
```

## Overview

When you set [`isCollaborationEnabled`](/documentation/ARKit/ARWorldTrackingConfiguration/isCollaborationEnabled) to true, ARKit calls [`session(_:didAdd:)`](/documentation/ARKit/ARSessionDelegate/session(_:didAdd:)) with an [`ARParticipantAnchor`](/documentation/ARKit/ARParticipantAnchor) for every user it detects in your physical environment, providing you with their world position.
