# AssetInstallationRequest

An object that describes, downloads, and installs a selection of assets.

```
@objc final class AssetInstallationRequest
```

## Overview

You do not create instances of this type directly; obtain them from [`assetInstallationRequest(supporting:)`](/documentation/Speech/AssetInventory/assetInstallationRequest(supporting:)).

The system consolidates download and installation requests; you may obtain several of these instances and call [`downloadAndInstall()`](/documentation/Speech/AssetInstallationRequest/downloadAndInstall()) several times without causing redundant downloads.

## Topics

### Performing an installation request

[`func downloadAndInstall() async throws`](/documentation/Speech/AssetInstallationRequest/downloadAndInstall())
