# ARSession.CollaborationData

An object that holds information that a user has collected about the physical environment.

```
class CollaborationData
```

## Overview

To create a multiuser AR experience, you enable collaboration on a world tracking session. ARKit regularly outputs [`ARSession.CollaborationData`](/documentation/ARKit/ARSession/CollaborationData) that users share with each other, which enables everyone to view the same virtual content from their own perspective. For more information, see [`isCollaborationEnabled`](/documentation/ARKit/ARWorldTrackingConfiguration/isCollaborationEnabled).
