I went in to my account. Did everything as you wrote. Did not update, adjusted manually 8.0. But the mistakes are still the same. I do not understand what the reason may be. Previously, this was not. When I build a project on another Mac, where Xcode 7.2.1 then everything works. I uploaded a .mfa file with one level of the project. Can you test your Xcode?
Check all your provisioning profiles in your Apple developer account, check if they are valid/expired condition, maybe the one use is expired.
... new things are coming ...
I am very grateful to all of you for your help.
