what are the steps to turn on Livi Activities for Apple Watch ?

To turn on Live Activities for Apple Watch, follow these steps:

1. Update to watchOS 11 and iOS 18: Ensure that your Apple Watch is running watchOS 11 and your iPhone is running iOS 18. Live Activities will appear in the Smart Stack on Apple Watch automatically after these updates.

2. Review Your Live Activity: Check how your existing iOS Live Activity appears on Apple Watch. This can be done using the Xcode preview for your Live Activity by adding the supplemental activity families modifier. This will allow you to see how your Live Activity will be displayed on Apple Watch (Bring your Live Activity to Apple Watch).

3. Customize for Apple Watch: If you want to provide a custom Live Activity view for Apple Watch, you can modify your Live Activity to use the supplemental activity families. This customization can be previewed in Xcode using the canvas device settings (Bring your Live Activity to Apple Watch).

4. Ensure Compatibility: Make sure your dynamic island compact views are timely, relevant, and informative. Use the environment to further customize your Live Activity view when it appears on Apple Watch (Platforms State of the Union).

5. Launch Watch App from Live Activity: If you have a watchOS app, you can opt to open it from a tap on the Live Activity in the Smart Stack. In the build settings for your watch app target, add a value for the supportsLaunchForLiveActivity attributes type key in the info plist section to launch your watch app for all your Live Activities (Bring your Live Activity to Apple Watch).
