At WWDC 2024, Apple introduced a new way to broadcast updates for Live Activities using a single push notification. This feature allows developers to send updates to a large audience efficiently. Instead of managing individual push tokens for each user, developers can now use broadcast push notifications to update Live Activities for multiple users simultaneously. This is particularly useful for scenarios where many people are following the same event, such as a sports game or a flight update.
To implement this, developers need to create a channel for the event and obtain a unique channel ID. The app can then subscribe to updates on this channel, and the server can send a single push notification to update all subscribed devices. This method ensures that everyone receives the latest information with minimal effort.
For more details, you can refer to the session Broadcast updates to your Live Activities (08:39).
