How to enable the Apple Intelligence with Siri Intents?

To enable Apple Intelligence with Siri Intents, you need to integrate your app using the App Intents framework. Here are the key steps and concepts:

App Intents Framework: This framework allows you to define a set of actions for Siri, Shortcuts, and other system experiences. It is particularly useful if your app does not overlap with an existing SiriKit domain.
Defining App Intents: You can start by defining your app's capabilities using app intents. This will enable users to interact with your app through Siri and the Shortcuts app. Over time, Siri will gain the ability to call these app intents that fall into supported domains.
Semantic Search and Indexed Entities: With Apple Intelligence, Siri can perform semantic searches within your app. You can define entities using the IndexedEntity API to provide additional context, allowing Siri to search your app's content more effectively.
New Siri Capabilities: Siri can now invoke any item from your app's menus and understand more natural language, even if the user stumbles over their words. This is part of the enhanced conversational capabilities provided by Apple Intelligence.
App Intent Domains: Apple has introduced app intent domains, which are collections of app intent-based APIs designed for specific functionalities like books, camera, or spreadsheets. These domains include a broad set of new actions that support flexible voice interactions.
