I just tried Beta 3 of Xcode and iOS 16, same issue.

That is feedback, but a button should "feel" like other buttons especially the big ones with the long title text in them.

I plan on watching that and all the videos (I am such a nerd). I was going through the documentation that was released yesterday but did not see anything that aligned with the LargeContentViewer features. I do see when building a test app that the LargeContentViewer is definitely a think in SwiftUI because TabView uses it as expected.
