# AVAssetTrackGroup

A group of related tracks in an asset.

## Declaration

class AVAssetTrackGroup
```

## Overview

Overview A track group describes a group of related alternative tracks, only one of which should play at a time. Groups of alternative tracks typically contain variations of the same content, like subtitles in multiple translations.
