Recommendation on How to Learn More on Using Various Xcode Debugging Panes

I don’t have a fundamental background in Computer Science or Computing Engineering. I want to learn more about how to do code debugging, but within the bounds of how Xcode provides various debugging panes. I’ve seen a number of WWDC session videos about Xcode and debugging. However I really need to learn more about the fundamentals of using Xcode panes like the stack trace pane, the variables pane, and the debugging console. I would greatly appreciate any advice on tutorials, videos, WWDC sessions, etc. that go to the basic levels of what these panes show, how to interpret the content, and how to interact with the information in various Xcode debugging-related panes. Thank you.
