how to implement rich push notifications

To implement rich push notifications, you can utilize the new broadcast push notifications feature introduced at WWDC 2024. Here's a step-by-step guide based on the session "Broadcast updates to your Live Activities":

1. Enable Broadcast Capability: First, enable the broadcast capability for your app in the developer portal under the push notifications section.

2. Create a Channel: Use the push notifications console to create a channel for your event. This channel will have a unique channel ID that your app will use to subscribe for updates, and your server will use to send updates.

3. Subscribe to Updates: In your app, leverage ActivityKit to subscribe to live activity updates using the new channel push type.

4. Send Broadcast Push Notifications: Use the push notifications console to send a broadcast push notification. You can configure the notification with a payload that includes the necessary information, such as scores or updates, and send it to all subscribers of the channel.

5. Manage Channels: Use the channel management API to manage the lifecycle of channels. This includes creating, deleting, and maintaining channels as needed.

For more detailed instructions, you can refer to the session Broadcast updates to your Live Activities (08:39) which covers how to send broadcast push notifications.
