If the root cause of a bug isn’t immediately obvious when inspecting your source code, watching your variables change as you step through the code helps you isolate where the bug is occurring so you can investigate the possible cause for it. The Xcode debugger provides several methods to step through your code and inspect variables. You can precisely control execution of your code from a breakpoint, stepping into and out of called functions as necessary to determine where your bug occurs. You can monitor variables while stepping through code, or pause execution to inspect them more closely. Start your investigation at a breakpoint when your app is in a known good state before the bug occurs, at a point where you think the bug may be about to happen.
