Some days ago I installed Xcode 5. Today I'm trying to submit an app, but during validation I'm getting this issue: "The network connection was lost". I've never had any problem with Xcode 4.

My network is OK and I'm not using any proxy.

What is causing this problem?


It might have been a coincidence, but like other recent xcode issues I solved this by restarting xcode.


For me the solution was to submit the app via Application Loader (downloadable directly from iTunes Connect) rather than Xcode.
