App Intents

App Intents: Define and expose your app's functionality to the system, powering Shortcuts, Siri, and other system services.

App Intents is Apple's modern framework for integrating your app's features directly into the system. It replaces the older Intents and Intents UI frameworks, offering a unified and streamlined approach. With App Intents, you define the actions users can perform within your app (e.g., 'order a coffee,' 'start a workout'). These definitions automatically make your app's capabilities available across the OS, including Shortcuts, Siri, Spotlight, and even the Action button on iPhone 15 Pro. This means users can trigger your app's functions with voice commands, custom automations, or system-wide searches, significantly enhancing discoverability and user experience. It's a declarative API, making it easier to maintain and extend your app's system integrations.
