Updates to core location

In the session titled "What’s new in location authorization" at WWDC 2024, several updates to Core Location were discussed. Here are the key points:

1. CL Service Session: A new declarative way to manage location authorization goals. It simplifies the process of handling location permissions by allowing developers to define what authorization is needed for each feature of their app.

2. Implicit Service Sessions: Core Location can now treat the act of iterating live updates or monitor events as implicitly holding a CL service session. This means that apps can handle location authorization with less code, as these sessions are managed automatically.

3. Diagnostic Properties: New diagnostic properties have been introduced to provide more context when location updates or events cannot be delivered. For example, properties like accuracyLimited and locationUnavailable help developers understand why updates might not be arriving.

4. Session Lifecycle: The session lifecycle is aligned with user-facing features, and Core Location can resume or relaunch the app into the background when new information is ready, provided the app's authorization allows it.
