I found 100 days of Swift UI. It is good. I have also found some instructional video's on the web. While I was looking I couldn't find Liquid Glass button modifiers / code.

I have searched that phrase "intro to app development with swift" and there were no exact matches. I tried to contact apple support and they referred me to the forums and user created content. I'm on the brink of using one of my two code level supports or not renewing my developer account at all. I really want to use Xcode though instead of third party tools. Can someone please post links to MacOS development educational material.
