Xcode 7.1 "iTunes store operation failed you are not authorized to use this service"
I met the same issue today and I think it is a bug of Xcode 7.1
Finally I managed to submit my app via Application Loader. There were warnings but it did work.
Here are the basic steps:
- Xcode menu --> Xcode --> Open Developer Tool --> Application Loader
- Double click "Deliver Your App" and choose the file exported in step #2
- click next and follow the instructions until the end
In mi case, it seems that updating to Xcode 7.1 removed some account information. So, after a few attempts to upload it from Xcode, I opened Application Loader, and it asked me to login. I logged in and finally could submit to the App Store from the Organizer. Hope it helps someone.
