Hello Brian, my sincere congratulations on a great course. Your learn-by-doing teaching style is superb, as is your attention to detail. Definitely top-notch. I have one question, though, not at all related to programming: I could not find any of the "links down below" for things such as a more in-depth explanation of tuples (lesson 18), or DispatchQueues, or whatnot. Are the links on another, perhaps earlier, platform where you placed your courses?
