Thank you Dirk-FU. In retrospect, your explanation makes sense and I am beginning to wrap my head around declarative vs. imperative programming.

Never mind... I figured it out by trial and error. Thanks for looking.
Please see trivial example of above issue with NavigationSplitView not working on smaller iPhones. Works as expected on iPads and iPhone Pro max, but the detail view does not appear on SE, Xr... and smaller iPhones. Should see a simple parabola on the detail view and the text "This is the sidebar view" in the sidebar. When you run the code, the detail view will appear first on the large iPhones. When you run the code on smaller iPhones, only the sidebar will appear. Thank for taking a look.

Thank you for the link regarding NavigationSplitViewColumn. Unfortunately, this function is in beta and not available until the release of iOS 17. I may release the App for iPad(iOS) and macOS and re-release for iPhone(iOS) when iOS 17 becomes real.
