# setExposure

The app intent conforms to the schema for setting the exposure of an asset.

## Declaration

```swift
var setExposure: some AssistantSchemas.Intent { get }
```

## Overview

Overview Use Swift macros that generate additional properties and add protocol conformance for your app intent implementation. The following example shows an app intent that conforms to the .photos.setExposure schema: @AppIntent(schema: .photos.setExposure) struct SetMediaExposureIntent: AppIntent {     @Parameter     var target: PhotoEntity

@Parameter     var value: Double?
