Which WWDC push notification was introduced

The new push notification introduced at WWDC 2024 is the broadcast push notification. This feature allows developers to send updates for live activities to a large audience with a single push notification. This is particularly useful for scenarios where many people are following the same event, such as a sports game or flight updates.

Here are the key points about broadcast push notifications:

• Efficiency: Instead of sending individual push notifications to each user, a single broadcast push notification can be sent, and APNs will deliver it to all subscribed devices.
• Channels: Each event that needs updates is associated with a unique channel. Devices subscribe to this channel to receive updates.
• Implementation: Developers need to enable the broadcast capability in the developer portal and create channels using the Push Notifications Console.
