Submitting to the App Store stuck at “Authenticating with the iTunes Store” in XCode
If while try to submit your application to appstore your XCode stuck at “Authenticating with the iTunes Store” try this trick, it fixed it for me.
Open Terminal and run:
– go to your home with this command cd ~
– rename itmstransporter folder with this mv .itmstransporter/ .old_itmstransporter/
– and finally run this command “/Applications/Xcode.app/Contents/Applications/Application Loader.app/Contents/itms/bin/iTMSTransporter”
iTMSTransporter will then update itself, then you can try uploading in XCode again. That’s All.
