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
