On Apple's developer website, they list: Xcode 26.2 RC (17C48) from date December 3, 2025.

The downloaded file is called Xcode_26.2_Release_Candidate_Apple_silicon.xip

I installed this on December 7, 2025.

In Xcode, the About Xcode says Version 26.2 (17C48)

When I build a new archive for an update of an existing app, it validates and "distributes" to Appstoreconnect fine.

However, in Appstoreconnect, when I try to submit the app for review, I get error:

Unable to Add for Review
The items below are required to start the review process:
This build is using a beta version of Xcode and can’t be submitted. Make sure you’re using the latest version of Xcode or the latest seed release found on the releases tab in News and Updates

I have no idea what's wrong. My Xcode is not beta version.

In appstoreconnect, the build metadata says Build SDK is 25C54

I have tried bumping up the version and build number 3 times. I have done "Clean Build Folder". No luck.

Is anyone else facing this issue with the new Xcode?
