relativeFontChange

The relative change of the font for rendering a book.

Declaration

var relativeFontChange: some AssistantSchemas.Enum { get }

Overview

Use Swift macros that generate additional properties and add protocol conformance for your app enum implementation. The following example shows an app enum that conforms to the .books.relativeFontChange schema:

@AppEnum(schema: .books.relativeFontChange)
enum BookRelativeFontChange: AppEnum {
    case increase
    case decrease

    static var caseDisplayRepresentations: [BookRelativeFontChange: AppIntents.DisplayRepresentation] = [
        .increase: "Increase",
        .decrease: "Decrease",
    ]
}
