To use CoreLocationSessionActivityBackground, you need to understand the concept of CL service sessions introduced in the session "What’s new in location authorization" at WWDC 2024. Here are the key points:

  1. CL Service Sessions: These are declarative ways to tell CoreLocation your authorization goals and what you need for each feature of your app while it is running. This helps manage location authorization more robustly and efficiently.

  2. Session Lifecycle: You should create CL service sessions when your app is in the foreground. These sessions can continue to be effective even if the app is later suspended or terminated, as long as the session was started in the foreground or while another session was in effect. This ensures that CoreLocation can restore authorization if needed when the app comes back to the foreground.

  3. Implicit and Explicit Sessions: Implicit sessions are created automatically when iterating live updates or monitor events. However, for more control, you can create explicit service sessions, especially if you need full accuracy or always authorization. This can be done by setting the NSLocationRequireExplicitServiceSession key in your app's Info.plist.

  4. Handling Background and Termination: CoreLocation can continue to act on a session even if the app is terminated, and it will resume or relaunch the app into the background when new information is ready for delivery, provided the app's authorization allows it.

For more detailed information, you can refer to the session chapter on Session lifecycle.
