My answers aim to be precise and helpful by providing relevant information from the WWDC sessions. If you find them vague, it might be because the context provided is limited or the question is broad. Here are some specific details from the sessions mentioned:

  1. Analyze heap memory:

    • This session covers various aspects of memory management, including types of references (strong, weak, unowned, unmanaged, and conservative) and how the Xcode memory graph debugger works. It also discusses common issues like why leaks might not always be detected and how to handle non-returning functions that appear to leak memory.
    • For example, the session explains that weak references are always optional types and become nil after their destinations are deinitialized, while unowned references directly hold their destinations and can cause deterministic crashes if accessed after deallocation (Analyze heap memory).
  2. What’s new in location authorization:

    • This session introduces CL service sessions, which allow CoreLocation to understand your app's authorization needs and act accordingly. It also discusses diagnostic properties that help you understand why location updates or events might not be yielded.
    • For instance, CL service sessions should be taken proactively to ensure that CoreLocation knows your goal and can act when next possible (What’s new in location authorization).
  3. Migrate your app to Swift 6:

    • This session focuses on migrating apps to Swift 6, emphasizing data-race safety and concurrency features. It highlights the importance of local reasoning guarantees to prevent data races and ensure that changes in one part of the app don't break other parts.
    • For example, Swift concurrency makes guarantees explicit, helping to avoid issues like callbacks coming in on unexpected queues (Migrate your app to Swift 6).
