Guidance on iPhone Duo Supported Builds - For Review

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.
