Live Broadcast(

The session titled "Broadcast updates to your Live Activities" at WWDC 2024 introduces a new way to broadcast updates for live activities to a large audience using a single push notification. This is particularly useful for scenarios where many people are following the same event, such as a sports game. The session covers how to use broadcast push notifications to update live activities on multiple devices efficiently.

Key points from the session include:

• Introduction to Broadcast Push Notifications: This new feature allows developers to send a single push notification to update live activities for many users simultaneously, without managing individual push tokens for each user.

• Creating and Managing Channels: Developers can create channels for specific events, like a soccer game, and use these channels to send updates. The lifecycle of a channel is independent of the live activity, meaning it can be reused for subsequent activities.

• Using the Push Notifications Console: The console is a tool for testing and integrating broadcast notifications. In production, servers should send requests directly to APNs using the new API.

• APNs Integration: The session explains how to integrate the new APNs API into your server to manage channels and send broadcast push notifications.
