Failed to submit app to iTunes Store
I just selected Standard Architectures in both Project and Target, and it worked for me.
I had the exact the same error, after hours of trying, adjusting all the parameters like the bundle ID or display name, etc. None of them worked.
Finally I got it work. Here is what I did.
I started all over by deleting all the records in keychain, certificates and provision profiles. And just added one certificate and profile for app distribution. There was only one record to make no confusion. And then boom, it uploaded successfully.
I guess my mistake was to submit multiple times of certificates or provision profiles earlier (although I deleted multiple entries but I did see something strange) because I thought the creation process was stuck so I refreshed the browser. Being patient in each steps will eventually saves more time! :) Good luck!
I got the same error today with xCode 7. I resubmitted with no changes and it went through. Probably Apple bug. I am letting you know that sometimes it is not an issue with our project/target settings.
