When trying to upload an App to iTunes connect in Xcode 8.3.3, I get the error:
iTunes Connect access for "Team-Name" is required. Add an account in the Accounts preference plane.
The account already exists and (in some cases) has been working without incident previously.
How do I get around this issue with Xcode so that I can upload my app to the AppStore?
When nothing works. Just restart your computer and try again! Nonsense but works like magic.
This happened to me when my app was rejected when uploading on AppStore (not sure if this could be connected).
I tried to remove and readd the Developer's account in XCode but that didn't help.
Then it started working after I replied to the Binary Rejected message on App Store Connect and restarted XCode. Not sure if that could be connected but it started working again instantly after those steps.
In My case none of the above solutions worked,
I have an access for both Developer account and iTunes Connect account, but I faced the same Issue.
The only option worked for me is updating my MAC OS before it was 10.13.4, after update to 10.13.6 the problem was resolved. Hope this will help to someone.
