# DataProvider

A source of live data from ARKit.

```
protocol DataProvider : AnyObject, CustomStringConvertible, Sendable
```

## Overview

Most providers supply an asynchronous sequence of updated anchors for the provider’s data type. For example, a [`HandTrackingProvider`](/documentation/ARKit/HandTrackingProvider) instance’s [`anchorUpdates`](/documentation/ARKit/HandTrackingProvider/anchorUpdates) property gives updates over time for hand anchors.
