UIKit content and updates lacking

I see that Raywenderlich is becoming more SwiftUI focused. While Combine and SwiftUI tutorials are excellent but there has been a lot changes in UICollection View, UIButton in the last 2 years of WWDC which are completely missing from the courses and books. There are countless organizations who are using UIKit primarily and moving away from this makes this website less robust.

Are there any chances of UIKit courses or books updates with the advanced changes?

Thank you for your feedback. This is currently being worked on.

As an update, check out the UIButton Configuration tutorial below:
