Hello!
So I updated my mac to 15.0 Sequoia Developer Beta and couldn't run Xcode 15.4 because of the Mac version mismatch, so I installed Xcode 16 beta and archived my app, but of course I cannot publish it to App Store because Apple doesn't let you do it with beta soft.
So, I downloaded Xcode 15.4 (current latest stable build) and managed to run it following this fix: https://stackoverflow.com/questions/69994916/how-can-i-run-older-xcode-version-on-new-macos-version
But, now when I create a new archive and submit it for review I am getting:
ITMS-90111: Unsupported SDK or Xcode version - App submissions must use the latest Xcode and SDK Release Candidates (RC). For details on currently supported versions, visit: https://developer.apple.com/news/releases.
I tried deleting derived data and build folders, building new archives, but to no avail.
Has anybody encountered this before?
