Debugging is a crucial part of software development, and Apple has presented several tools and techniques at WWDC to enhance this process. Here are some highlights from the sessions:

1. Xcode Essentials: This session covers various debugging techniques, including the use of breakpoints. You can set conditional breakpoints that only stop when a specific condition is true, allowing for more targeted debugging without frequent interruptions. Additionally, the session discusses using debugger expressions to log information without stopping the program, which can be useful for temporary logging without the need to rebuild the application. For more details, you can check the Debugging section.

2. Run, Break, Inspect: Explore effective debugging in LLDB: This session delves into using LLDB for debugging, focusing on techniques like backtraces, variable inspection, and expression evaluation. It introduces the p command, which has been reworked in Xcode 15 to streamline variable inspection and expression evaluation. The session also covers how to handle crash logs and use them to debug without running the program. For more insights, you can explore the Debugging as a search problem section.

3. Break into the RealityKit debugger: This session highlights the RealityKit debugger, which can display various types used in apps, helping developers visualize and debug complex systems. It provides tools to observe and manipulate the state of entities within RealityKit, which can be particularly useful for debugging augmented reality applications.

These sessions provide a comprehensive overview of the debugging tools and techniques available in Xcode and LLDB, helping developers efficiently identify and resolve issues in their code.
