@DTS Engineer Albert can you please help me with the same issue? I have xCode 26.2 and tools updated to the same latest version. I'm making build successfully. It appears in TestFlight in developer portal and then when I try to release TestFlight to external tester, I try to submit and get "This build is using a beta version of Xcode and can’t be submitted"... I tried to clear DerivedData, reinstall xCode, but still same issue.

Hi @Developer Program Support , can you please help to resolve 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. Nothing helps and I can't share my first app with volunteers to test. It's been almost a week since I opened a support ticket, but received no help yet.

Hi Albert, thank you for your response! I’m using Xcode Version 26.2 (17C52) Mac OS Tahoe 26.2 (25C56) Command Line tools are 26.2 as well. I tried to use my old Macbook to install different Xcode release versions 16.* and made build with those. That builds generate the same issue. I tried both auto-signing and manual signing with distribution profiles/certificates (https://ibb.co/Txq9my3v). That didn’t resolve the issue, got the same mentioned error: https://ibb.co/Y771kpbk

I have only one Xcode version on main Mac which is downloaded from App Store (latest one). I assume that's some kind of project file/app store connect account issue. Or simply weird issue only with Xcode 26.2 Waiting for tech support to take over my support requests (Senior advisor escalated it, but no tech team involvement for now).
