I was recently updating my matching game app for iOS and ran into a problem. As I was attempting to upload the bundle for review it kept getting stuck. The message on the screen was saying “Authenticating with the iTunes store” but it never completed. I attempted the upload several times and finally let it run all night. Still not uploaded. Doing a quick search I ran right into the solution.

The original solution was provided by AshHimself at Stack Overflow.

The solution is required a force update of the transporter application.

Here are the steps: Fire up a terminal window and change to your home directory. cd ~

Make a backup of the current transporter directory. mv .itmstransporter/ .old_itmstransporter/

Run the iTMSTransporter to allow it to update itself. This can take a couple of minute so be patient. "/Applications/Xcode.app/Contents/Applications/Application Loader.app/Contents/itms/bin/iTMSTransporter"

Once the update is complete you should be able to run XCode and try the upload again.

This process worked great for me and I was able to finally upload my app. It just got approved today. You can find it on the app store here. Harold’s Holiday Matching Game
