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?
I had to create virtual machine with Sonoma , install Xcode 15, then from the main machine with Sequoia but running Xcode 15, ( can be the same done in Xcode 16 this part ) create a provisioning profile, export developer profile from Xcode , export the two certificates I saw on my system keychain access regarding to apple developer. On the virtual machine (Sonoma), import the certificates exported from the keychain , add it to System ( not to login ) , in Xcode, import the developer profile, in the App general, instead of Xcode managing the provisioning profile, select to import and select the provision profile you made at developer.apple.com ( be sure to select iOS , on the devices show all and select all Macs and phones.. and everything ;) Then create the Archive, right click + show in finder. copied the xarchive to my sequoia os machine, and upload from there
