LLDB Debugging
Interactive debugging with LLDB. The debugger freezes time so you can interrogate your running app — inspect variables, evaluate expressions, navigate threads, and understand exactly why something went wrong.
Core insight: "LLDB is useless" really means "I don't know which command to use for Swift types." This is a knowledge-gap problem, not a tool problem.
