What's the guidance on submitting new builds for App Review that include support for iPhone Duo/iPhone resizability? Will they work when building with Xcode 27 + if available for 27.1 or do we have to wait for new Xcode release?

Any guidance from Apple and timeframe on build submission if our updates are ready and undergoing testing in simulator?

Thank you.

If you use horizontalSizeClass and verticalSizeClass to check for the regular/compact size, then that is fine.

For anything that needs APIs for SDK 27.1, e.g. ArrangementView, typically you would need to wait for the Release Candidate of Xcode 27.1, that's when they say developers can submit apps build with 27.1.
