I used to spend so much time watching different YouTubers trying to really understand SwiftUI. Then I came across one of Mike’s articles on Medium, loved the way he explained things, and decided to take the risk and buy the Complete Bundle. Yes, it’s not cheap, but after going through it, I can honestly say it’s worth every penny. The structure, the narrative, the demo project, the documentation… everything is incredibly well thought out. I absolutely love it. Easily one of the best investments I’ve made in learning SwiftUI!!!!!!!!!
