About LLDB and Debugging
A guide documenting the LLDB command-line debugger
At a Glance
A debugger has two primary functions: controlling execution flow and accessing state .
You primarily control the execution of a program by setting breakpoints at different locations in code. Whenever a program hits a set breakpoint, the debugger temporarily stops execution of the program. While the execution is stopped, you can use the debugger to inspect or modify the current state of different variables, step over, into, or out of the next statement, and continue execution as needed.
