# trackGroups

The track groups an asset contains.

## Declaration

static var trackGroups: AVAsyncProperty<Root, [AVAssetTrackGroup]> { get }
```

## Discussion

Discussion Use the load(_:isolation:) method to retrieve the property value. The value is an empty array if the asset has no track groups.
