The Human Interface Guidelines say, "For iOS, iPadOS, and watchOS, you can tell Xcode to generate all sizes from your 1024×1024 px App Store icon". However, I can't find a way in Xcode to do this.
For example, if I just put my 1024x1024 app store icon in the app store well in my AppIcon in my Assets.xcassets and then build, the simulator shows a generic app icon.
Any idea what I'm missing?
Thanks,
John

In case you're still trying to figure this one out, or in case anyone else has found their way here with the same problem. All you need to do is select your icon and then in the Inspector select "Single Size".
WWDC22's "What's New in Xcode" had a short section covering this new feature. Here is a direct-time link for you: https://developer.apple.com/wwdc22/110427?t=1219
