This lecture really scratched my itchy parts so refreshingly. I had been working on the layout without properly understanding the principles with the knowledge I had obtained here and there, but now I don't have to do that anymore. This one lecture really solved all the parts I had been curious about. I blew away my past self who relied on auto scaling, and now I can work really cleanly (and comfortably and easily) with auto layout. In my iOS development career, I think today's lecture will be a big turning point, to the point where I can divide it into before and after taking this lecture. Thank you so much for the great lecture. Now I trust it!! I'm going to sign up for Swift UI!! ㅎㅎ
