Hi,

We ship an iOS and iPadOS app distributed on the App Store. We understand new submissions will be required to use the Xcode 27/iOS 27 SDK starting around April 2027 (following the same pattern as the iOS 26 SDK requirement from April 2026), after which the UIDesignRequiresCompatibility flag will no longer be available.

Is there an exact date this takes effect? Specifically, will submissions built with Xcode 26 still be accepted in March 2027, or is the cutoff earlier?

Thank you.

Thanks for the post.

We completely understand that knowing the exact date is highly important for your team's roadmap.

However, per policy, we are unable to disclose, confirm, or comment on exact dates for future SDK requirements and App Store submission cutoffs before they are officially announced.

I sugguest keeping an eye on the Apple Developer News and Updates page like the release notes.

and

Thank you for your understanding.
