how do i use CLBackgroundActivitySession

To use CLBackgroundActivitySession, you need to understand the concept of CoreLocation service sessions, which are designed to manage location authorization and updates more effectively. Here are the key points to consider:

1. Service Sessions: CLBackgroundActivitySession is a type of service session that allows your app to continue receiving location updates even when it is in the background. This is particularly useful for long-running tasks like tracking a workout.

2. Explicit vs. Implicit Sessions: You can create explicit service sessions to assert your app's continued interest in location updates. Implicit sessions are automatically managed by CoreLocation based on your app's activity.

3. Authorization Goals: When creating a CLBackgroundActivitySession, you need to specify your authorization goals. For example, if you need full accuracy or always authorization, you should explicitly request it.

4. Lifecycle Management: Service sessions, including CLBackgroundActivitySession, should be managed proactively. This means creating and holding sessions when your app needs them and ensuring they are properly resumed if the app is suspended or terminated.

For more detailed information, you can refer to the session "What’s new in location authorization" from WWDC 2024. Specifically, the section on session lifecycle starting at 09:25 provides insights into how to manage these sessions effectively.
