Hi, I really need help to resolve the issue with submitting build made with 26.2 for review to release TestFlight build to external testers. I'm always getting "This build is using a beta version of Xcode and can’t be submitted". I tried everything from cleaning DerivedData to fully reinstalling Xcode and tools to 26.2. Even tried earlier Xcode release versions and after pressing Submit for review I always face the same issue. Nothing helps and I can't share my first app with volunteers to test. By Jan 6 2026, my Xcode 26.2 is up to date with App Store and in Xcode Organizer I choose App Store Connect and press Distribute.
Xcode 26.2: Can't submit build to external testers via TestFlight
Thanks for your post.
Facing an error stating "This build is using a beta version of Xcode and can’t be submitted" can be frustrating, especially when you're ready to share your app with testers. Double-check that you're using a release version of Xcode, not a beta, what’s your build? Please remember Xcode 26.2 got released 3 weeks ago. Can you provide me this?.
Sometimes, what appears to be the latest version might still have beta components. Ensure your macOS version is supported by the Xcode version you're using. Can you also provide me the build number for your macOS? In Xcode, check your project's build settings. Ensure that you're using a distribution certificate for signing, not an ad-hoc or development certificate. Ensure no beta versions of Xcode beta are installed or active on your system.
Check Applications and remove any beta installations of Xcode.
Hope this helps
