Today I encountered a problem when trying to submit an app to the iTunes App Store.
Authenticating with the iTunes Store
The message stayed on my screen for a whole lunch hour. Usually excuses like this allow developers to refer to the infamous xkcd: Compiling it can get a little aggravating not knowing exactly what is going on.
If you're ready to submit your app to iTunes and suddenly find yourself staring at this message for more than 10 minutes, give the following Terminal commands a trick.
cd~
mv .itmstransporter/ .old_itmstransporter/
"/Applications/Xcode.app/Contents/Applications/Application Loader.app/Contents/itms/bin/iTMSTransporter"
These three lines move your itmstransporter profile to a backup location and then attempt to update the
iTMSTransporter components.
Job done.
