App Store Connect (May 5, 2026): you can now upload apps built with Xcode 26.5 RC
Apple updated App Store Connect to accept uploads built with Xcode 26.5 RC (and the 26.5 RC SDKs) for App Store submissions and TestFlight testing. It’s a small line item, but it’s the kind that silently unblocks launch timelines.

What changed
Apple updated App Store Connect so you can now upload apps built with Xcode 26.5 RC using the 26.5 RC SDKs (iOS, iPadOS, macOS, visionOS, tvOS, watchOS) for:
- App Store submission
- internal TestFlight testing
- external TestFlight testing
Why this matters (for growth teams, not just engineers)
This is “release engineering” news, but it directly affects marketing execution.
When a new SDK becomes the baseline for compatibility, you typically get a short window where:
- a build must move to the new toolchain,
- QA and review cycles stretch,
- and store work (new screenshots, CPPs, IAE timing, messaging) gets squeezed.
If App Store Connect has not yet flipped support, you can be ready technically and still be blocked operationally.
Tiny win
Before your next launch, do a 20-minute “toolchain readiness” check:
- confirm which Xcode/SDK your next release will ship with
- confirm App Store Connect currently accepts that toolchain for App Store + TestFlight
- if you are switching, lock your marketing asset freeze date (screenshots, CPPs, IAE copy) to the build date, not the press date
