ITMS-90725: since 2026-04-28 App Store uploads must be built with Xcode 26 and an iOS 26-family SDK

ITMS-90725
Fix
  • Build with Xcode 26. On GitHub-hosted macOS runners select it explicitly, e.g. sudo xcode-select -s /Applications/Xcode_26.<x>.app (check the runner image's installed list).
  • Your deployment target (minimum iOS your users need) is independent; keep IPHONEOS_DEPLOYMENT_TARGET as low as you support.
  • For engines/frameworks (React Native/Expo, Flutter, Unity, Unreal, Capacitor) upgrade to a version validated with Xcode 26 and confirm the produced binary's SDK.

Symptom

An iOS/iPadOS/tvOS/visionOS/watchOS build uploaded to App Store Connect or TestFlight is flagged with ITMS-90725 (SDK version) or rejected because it was built with Xcode 16 / the iOS 18 SDK. CI images or engine toolchains pinned to Xcode 16 are the usual cause.

Cause

Apple's SDK minimum requirement, in effect since 2026-04-28: "Apps uploaded to App Store Connect must be built with Xcode 26 or later using an SDK for iOS 26, iPadOS 26, tvOS 26, visionOS 26, or watchOS 26." The previous floor (since 2025-04-24) was Xcode 16 / iOS 18 SDK. A user report on the Unreal Engine forums shows a build stamped with the iOS 18.1 SDK triggering ITMS-90725 after the deadline.

Verify

xcodebuild -version prints Xcode 26.x in CI; in the built app, plutil -p Payload/App.app/Info.plist | grep DTSDKName shows an iphoneos26 SDK.
