Thank you for pasting that code. I don't understand what I may be doing wrong.

So to answer your questions: 1). What's new in SwiftUI? WWDC 2022. 2). I am able to copy the code at 28:49 regarding the new Shape Styles Icon Grid. 3). At 32:04 When I copy the code on Layout: Seating Chart Layout, and then paste it into a project. Only the code that was copied for the new Shape Styles Icon Grid pastes. I have cleared the clipboard using the Terminal, restarted my Mac and the Developer App. So far I have not been able to make this work. Bob
