This is the first time ever I upload an App and I'm getting crazy, I open Application Loader and follow the steps, I select an ipa file and then I get the following errors:
What I understand is that I'm missing some kind of certificate or something like this, how can I fix this? If I try to upload my app trough XCODE I can't because:
I go to my Archived app -> Distribute -> appstore -> and it says that IM mising some identities, so...
If someone please help me and explain the process of uploading the app
Thanks!
