updateFontSize

The app intent conforms to the schema for updating the font size.

Declaration

var updateFontSize: some AssistantSchemas.Intent { get }

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 .books.updateFontSize schema:

@AppIntent(schema: .books.updateFontSize)
struct UpdateBookFontSizeIntent: AppIntent {
    @Parameter
    var target: BookSettingsEntity

    @Parameter
    var changeOperation: BookRelativeFontChange

    func perform() async throws -> some IntentResult {
        .result()
    }
}
