Firstly, I uploaded the assembly to the AppStore using Xcode 7 beta and only after clicking "Submit for review" did it show me the following error:
Invalid Toolchain. New applications and application updates must be created using the (GM) version of Xcode 6 or later and the iOS 8 SDK or later. Do not submit applications created using the beta version.
So, I updated to the latest version 7.0.1, archived the assembly, uploaded it to the App Store.
And guess what? It shows the same error.
I looked through the forum, tried to open the plist file archive assembly, but the line "BuildMachineOSBuild" already contains "14F27" (this worked for other guys on the forum).
Apple forums are populated with cases of this error, and no one has a clue.
NB: Apple had already resolved the problem about an hour ago. They reacted pretty quickly.
