Submitting to the App Store stuck at “Authenticating with the iTunes Store” in XCode

If your XCode is stuck at this step and no matter how many restarts or new attempts doesn’t fix it, you can try:

• XCode (menubar) → Open developer tool → Application Loader
• Sign in with your Apple ID
• Exit Application Loader
• Try submitting again the usual way
• Problem solved! :)

Update 15 May 2017: In case it’s still stuck please see here for part 2.
