how to inspect and solve a fluency problem

To inspect and solve a fluency problem in your code, you can utilize effective debugging techniques as discussed in the session "Run, Break, Inspect: Explore effective debugging in LLDB" from WWDC 2024. Here are some steps you can follow:

Reproduce the Bug: The first step in debugging is to reproduce the bug. This might involve running the application under a debugger like LLDB or using crash logs to understand the state of the program at the time of the crash.
Use Breakpoints: Set breakpoints at strategic points in your code to pause execution and inspect the program state. This can help you identify where things are going wrong. You can set breakpoints before a suspected faulty function or use high-firing breakpoints to catch errors in frequently executed code.
Inspect Variables: Use the p command in LLDB to inspect variables and evaluate expressions. This command has been enhanced to save time by combining multiple tools under a single command.
Analyze Logs: If your codebase uses logging, analyze the logs to trace the program's execution path and identify where the problem might be occurring.
Use Swift Error Breakpoints: If you suspect a Swift error is causing the issue, you can set a Swift error breakpoint to stop the application as soon as an error is thrown.
Iterate: Debugging is often an iterative process. You may need to run, break, and inspect multiple times, adjusting your approach based on what you discover.

For more detailed guidance, you can refer to the session Run, Break, Inspect: Explore effective debugging in LLDB (00:01:02) which covers these techniques in depth.
