# Messages

Make your messaging app’s actions available to Apple Intelligence and Siri by adopting schemas for common messaging actions.

## Overview

Overview The .messages domain defines app schemas that provide a structured representation for common messaging actions and content. Apply schemas in the .messages domain to make your app’s messaging functionality available to Apple Intelligence and Siri. Each schema defines the requirements for intents, parameters, and results so people get a consistent experience across messaging apps. For example, a person can send a message on different apps that support the sendMessage schema with the same phrases. The following table maps example phrases that apply to each schema. Your app needs to support all of these schemas when it supports any one of them.  |   |   |   |   |   |  At build time, Xcode validates whether your app implements all the schemas in the group. tip: Xcode generates a template implementation when you type messages_ and select a schema from the suggestions list. For more information about making your app’s actions available to Apple Intelligence and Siri, see Apple Intelligence and Siri AI.
