# AssetPackManager

An actor that manages asset packs.

## Declaration

```swift
actor AssetPackManager
```

## Mentioned in

Reducing download and storage demands with localized asset packs

## Overview

Overview The first time that your code refers to the shared manager, Background Assets considers that your app is opting into automatic system management of your asset packs. important: When using the asset-pack manager, make sure that you also adopt the corresponding managed extension protocol, ManagedDownloaderExtension (for self-hosted asset packs) or StoreDownloaderExtension from StoreKit (for Apple-hosted asset packs). Not doing so is a programmer error.
