Heads up for folks looking at resizable iPhone apps on iOS 27:
If you use constraint variations in your storyboards to detect compact/regular widths, you have a lot of rework in your future. That is because on iPhone the horizontalSizeClass is always compact and your storyboard layouts will not change when the UI is resized. Instead, you will have to track size changes and update constraints in your own code.
Initially I thought this was a bug, but it's not: https://fatbobman.com/en/posts/from-size-class-to-available-space/
