App Store submissions now open for iOS 27, macOS 27, and the rest of the OS 27 lineup
Apple opened App Store Connect submissions for apps built with the Xcode 27 Release Candidate and the OS 27 SDKs, ahead of the September 14 public launches. macOS 27 is Apple silicon–only, and April 2027 brings new minimum SDK rules.
Apple has opened App Store submissions for apps and games built for iOS 27, iPadOS 27, macOS 27, tvOS 27, visionOS 27, and watchOS 27 — the final developer gate before Monday’s public software rollout.
In a Developer news post, Apple says developers can download the Xcode 27 Release Candidate, build with the latest SDKs, test in TestFlight, and submit for App Review. The company frames the window as the moment to ship updates that take advantage of Apple Intelligence, the Foundation Models framework, design refreshes, and new App Store creative features.
What to do now
- Build and submit with Xcode 27 RC and the OS 27 SDKs
- Test thoroughly in TestFlight before App Review
- Prepare product page assets for the new product page headers and search result placements, using Apple’s updated templates and the coming product page preview tool in App Store Connect
- Answer the updated age rating questions — apps with social media capabilities must declare them so they align with Time Allowances for parents
macOS 27 is Apple silicon only
Apple reiterated that macOS 26 is the last release supporting Intel Macs and Rosetta. macOS 27 will be Apple silicon only. Developers who want to limit distribution to Apple silicon Macs should set the Xcode build architecture to arm64 only, then rebuild and resubmit.
That reminder lands alongside the iOS 27 / companion OS launch on September 14 and our earlier watchOS 27 release notes rundown.
April 2027: new SDK floors
Apple also reconfirmed minimum upload requirements starting April 2027:
- iOS / iPadOS apps → iOS 27 & iPadOS 27 SDK or later
- tvOS apps → tvOS 27 SDK or later
- visionOS apps → visionOS 27 SDK or later
- watchOS apps → watchOS 27 SDK or later
Why it matters this week
With iPhone Duo developer resources already live and OS 27 shipping Monday, this is the practical “submit now so you’re ready day one” window for App Store updates — not another hardware rumor, but a clear utility beat for anyone shipping on Apple platforms.
