# AVCaptureDataOutputSynchronizer

An object that coordinates time-matched delivery of data from multiple capture outputs.

## Declaration

```swift
class AVCaptureDataOutputSynchronizer
```

## Overview

Overview Use this class when you need to capture media from multiple capture outputs and want to receive all data samples from the same timestamp in a single delegate callback. For example, when you use an AVCaptureDataOutputSynchronizer object to coordinate the output of AVCaptureVideoDataOutput and AVCaptureDepthDataOutput objects, you can easily match each captured video frame to depth information captured at the same moment.
