I'm trying to upload my iOS App to App Store but I have some issues to upload my .ipa file to iTunes Connect.
I'm trying to upload my .ipa file wheter through Application Loader or XCode and the uploading seems to be ok.
For a while if I look at Activity I see the build written "Processing" but immediately after iTunes Connect doesn't show the build and, when I check the delivery status of my App in Application Loader -> Window -> Delivery Status, I read that there was an
"Import Error"
with no description of the error that occurred.
Which could be the problem?
