I'm trying to submit an iOS PhoneGap app to the app store via Xcode 5.0.2 but I'm encountering problems at the final distribution stage. The app works perfectly on the simulators and devices that I've used and even passes the validation yet when I go to distribute it a number of errors pop up and the project's status is listed as "Failed Validation".

I've had no luck searching for these errors on-line and I don't understand how it passes validation when I click validate but somehow fails it when I go to distribute.

I see other Xcode submission problems are linked to [Apple server traffic](https://stackoverflow.com/questions/19096621/xcode-5-app-submission-issue) but I'm not getting any "network connection lost" errors.

I've seen some issues requiring a Java update for Xcode but they seemed to effect Xcode 4 and I'm using Xcode 5.

EDIT:
I forgot to mention that I'm using an iMac on a University network.
