Publication make the app crash

Honestly, XCode is not so great as an IDE (I usually use AppCode if I want to do actual work), but I still use it for archiving and publishing new versions. But what happens when the Apple servers are down? XCode crashes. I could tell that there is some problem with the connection thanks to the Application Loader app that fails as well (but doesn’t crash)
