To implement iOS Push Notifications, particularly for broadcasting updates to Live Activities, you can follow these steps as outlined in the WWDC session titled "Broadcast updates to your Live Activities":

  1. Enable Broadcast Capability: First, enable the new broadcast capability for your app. This can be done in the developer portal under the capabilities list for push notifications.

  2. Create a Channel: Use the Push Notifications Console to create a channel. Navigate to the channels tab and select "New Channel" to configure it with the environment and message storage policy.

  3. Use ActivityKit: Leverage ActivityKit in your app to subscribe to live activity updates using the new channel push type.

  4. Send Broadcast Push Notifications: Integrate the new API from APNs into your server to manage channels and send broadcast push notifications directly. This allows you to send a single push notification that APNs will deliver to all subscribed devices.

  5. Testing: Use the Push Notifications Console to test integration with broadcast notifications. For production, your server should send requests directly to APNs.

For more detailed guidance, you can refer to the session Broadcast updates to your Live Activities (08:39) which covers how to send broadcast push notifications to update live activities on multiple devices at once.
