# StoreDownloaderExtension

An app extension that uses the system implementation to schedule Apple-hosted asset-pack downloads automatically.

```
protocol StoreDownloaderExtension : ManagedDownloaderExtension
```

## Overview

You can optionally implement the inherited `ManagedDownloaderExtension` requirements, but don’t implement any of the inherited `BADownloaderExtension` requirements for which this protocol provides a default implementation.
