How can I make an interactive live activity?

To create an interactive live activity, you can follow these guidelines based on the sessions from WWDC:

Design for Apple Watch: Live activities on Apple Watch can be interactive. You can enable interactions like tapping a widget to perform actions, such as turning on a light. It's important to design your live activity to show only the necessary information to communicate significant states, like progress or actions required. For more details, you can refer to the session Design Live Activities for Apple Watch (00:02:43).
App Intents: You can use App Intents to create interactive snippets that can integrate with live activities. This allows you to build interactive elements, such as configuring a food order before sending it to a restaurant. For more information, check out the session Explore new advances in App Intents (00:00:55).
Widgets and CarPlay: Live activities can also be displayed in CarPlay, and you can customize their presentation for different environments. This involves using the Supplemental Activity Family to optimize the layout for smaller displays. For more insights, see the session What’s new in widgets (00:12:18).

By following these guidelines and utilizing the tools and frameworks provided by Apple, you can create engaging and interactive live activities for your apps.
