Question

I\'m trying to upload my app to iTunes Connect with Xcode. I chose product > archive, choose my account, it compiles and when I try to upload it hand for a long time on:

Answer 1

I solved this issue.

There is a checkbox "include bitcode" at the bottom of the Summary screen (when you validate Archive) or Send XXX to Apple screen (when you upload to App Store) where the Organizer show the Binary and Entitlements together with Provisioning Profile. In XCode 7 it is checked by default. I unchecked it and re-run Validation - worked fine. As soon as checked the checkbox back on, it started failing with same error.

I have also unchecked the other checkbox on the same screen - symbolis upload.

Successfully uploaded the binary using the Organizr just now.
