GoKawiilDevelopers can now submit apps built for iOS 27 and Apple’s other new operating system releases, ahead of their official rollout next Monday. Here are the details.
Developers can now submit iOS 27-ready apps
During yesterday’s “Surprise and Shine” event, Apple confirmed that iOS 27, iPadOS 27, macOS 27, tvOS 27, visionOS 27, and watchOS 27 will launch next Monday, September 14.
Today, Apple announced that developers can now download the Xcode 27 Release Candidate and submit apps and games built with the latest SDKs for approval.
Apple also took the opportunity to remind developers that macOS 27 will only support software built for Apple silicon:
Optimize your app for macOS 27. macOS 26 is the final release supporting Intel Mac computers and Rosetta — macOS 27 will be Apple silicon only. To limit your app to Macs with Apple silicon, set your Xcode build architecture to arm64 only, then rebuild and resubmit. Removing support for Intel-based apps lets you further simplify your development and optimize your app for Apple silicon.
Additionally, Apple reminded developers to answer the new age rating questions required for features such as Time Allowances, and encouraged them to prepare their App Store listings for the new product page headers and search result assets, with updated design guidance and templates available for product pages, screenshots, app previews, and In-App Events.
Finally, Apple reaffirmed that “starting April 2027, apps and games uploaded to App Store Connect need to meet the following minimum requirements”:
iOS and iPadOS apps must be built with the iOS 27 & iPadOS 27 SDK or later
tvOS apps must be built with the tvOS 27 SDK or later
