# resizeDocuments

The app intent conforms to the schema for resizing a document.

## Declaration

```swift
var resizeDocuments: 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 .reader.resizeDocuments schema: @AppIntent(schema: .reader.resizeDocuments) struct ReaderResizeDocumentsIntent: AppIntent {     @Parameter     var documents: [ReaderDocumentEntity]

@Parameter     var width: Double?

@Parameter     var height: Double?

func perform() async throws -> some IntentResult & ReturnsValue<[ReaderDocumentEntity]> {         return .result(value: [ReaderDocumentEntity()])     } } For more information about the .reader app intent domain, see doc:Making-document-reader-actions-available-to-siri-and-apple-intelligence.
