GoKawiilApple opens App Store submissions for iOS 27 and other new OS releases
Apple has begun accepting app submissions built with the iOS 27, iPadOS 27, macOS 27, tvOS 27, visionOS 27, and watchOS 27 SDKs ahead of their September 14 launch. Developers can now download the Xcode 27 Release Candidate to prepare their apps for approval before the public rollout.
GoKawiil's interpretation of the reporting above, not reported fact.
This gives developers a short window to update apps before the new operating systems reach consumers, including the shift to Apple silicon-only support on macOS 27, which ends Intel Mac compatibility entirely. It also sets the stage for stricter SDK requirements starting April 2027, meaning developers who delay updates risk losing App Store eligibility.
- Apple now accepts app submissions built for iOS 27 and other 2027 OS versions ahead of Monday's launch.
- macOS 27 drops support for Intel Macs and Rosetta, requiring Apple silicon-only builds.
- Starting April 2027, all new app submissions must use the latest respective OS SDKs.
