If you're dealing with an app crash, the session titled "Run, Break, Inspect: Explore effective debugging in LLDB" from WWDC 2024 provides valuable insights into debugging crashes using LLDB. This session covers how to handle crash logs, set breakpoints, and use backtraces to understand the control flow leading to a crash.
For instance, you can open a crash log in Xcode, which uses LLDB to create a debugging session with the state of the program at the time of the crash. This allows you to investigate the source of the crash by examining the highlighted line of code and using backtraces to understand the sequence of function calls that led to the crash. You can find more about this in the chapter on "Crashlogs & starting the program" in the session.
Additionally, the session "Xcode essentials" discusses setting breakpoints effectively, which can be crucial in stopping the app at the point of error to inspect the state of the program. This can be particularly useful if your app is regularly throwing and catching expected errors.
For more detailed guidance, you can refer to the following chapters:
Build a great Lock Screen camera capture experience
Find out how the LockedCameraCapture API can help you bring your capture application’s most useful information directly to the Lock Screen. Examine the API’s features and functionality, learn how to get started creating a capture extension, and find out how that extension behaves when the device is locked.
Analyze heap memory
Dive into the basis for your app’s dynamic memory: the heap! Explore how to use Instruments and Xcode to measure, analyze, and fix common heap issues. We’ll also cover some techniques and best practices for diagnosing transient growth, persistent growth, and leaks in your app.
Meet the Translation API
Discover how you can translate text across different languages in your app using the new Translation framework. We’ll show you how to quickly display translations in the system UI, and how to translate larger batches of text for your app’s UI.
Use CloudKit Console to monitor and optimize database activity
Discover the new observability features in CloudKit Console. Learn how to use Telemetry and Logging to troubleshoot and optimize your app. Find out how to set up alerts to monitor your application’s behavior and notifications to stay on top of the container events that are most important to you. To get the most out of this session, we recommend being familiar with CloudKit containers.
Run, Break, Inspect: Explore effective debugging in LLDB
Learn how to use LLDB to explore and debug codebases. We’ll show you how to make the most of crashlogs and backtraces, and how to supercharge breakpoints with actions and complex stop conditions. We’ll also explore how the “p” command and the latest features in Swift 6 can enhance your debugging experience.
What’s new in App Store Connect
Explore new features for discovery, testing, and marketing. Find out how to nominate your apps for featuring on the App Store, share exciting moments (like a version launch) with marketing assets generated for you, deep link to specific content in your app from custom product pages, use the latest enhancements to TestFlight, and more.
Design App Intents for system experiences
App Intents power system experiences in controls, Spotlight, Siri, and more. Find out how to identify the functionality that’s best for App Intents, and how to use parameters to make these intents flexible. Learn how to use App Intents to allow people to take action outside your app, and see examples of when to navigate into your app to show contextual information.
Support semantic search with Core Spotlight
Learn how to provide semantic search results in your app using Core Spotlight. Understand how to make your app’s content available in the user’s private, on-device index so people can search for items using natural language. We’ll also share how to optimize your app’s performance by scheduling indexing activities. To get the most out of this session, we recommend first checking out Core Spotlight documentation on the Apple Developer website.
Xcode essentials
Edit, debug, commit, repeat. Explore the suite of tools in Xcode that help you iterate quickly when developing apps. Discover tips and tricks to help optimize and boost your development workflow.
Discover media performance metrics in AVFoundation
Discover how you can monitor, analyze, and improve user experience with the new media performance APIs. Explore how to monitor AVPlayer performance for HLS assets using different AVMetricEvents, and learn how to use these metrics to understand and triage player performance issues.
