Just updated to Xcode 7.1 and getting this error. Was able to upload fine using 7.0.1
Clean project not work with me in XCode 7.2. But I solve the problem by export Archive and using Application Loader.
Step:
Archive you build.
In Organizer: Chose your archive.
Export "Save for iOS App Store Deployment".
Open Application Loader (Xcode -> Open Developer Tool -> Application Loader: Download it if you don't have).
Select "Deliver your App" -> Select your exported ipa.
Upload.
=> Done
I tried most of the things here, but what finally did it for me was using the Application Loader instead of trying to upload my app from the Organizer.
Once I did it from the Application Loader I got an error message related to this: ITMS-90535 Unable to publish iOS app with latest Google Signin SDK, which was the real cause of the error.
After trying a few things, this is what worked for me:
You can use Application Loader to upload your build and solve it!
I had this problem for all night. Got
Had the same issue and tried everything including Application Loader but still would not load into iTunes Connect. I'm running XCode 7.1.1 and OS X El Capitan.
I also have Avira (free version) installed and once I disable it, everything went through. Hope this helps someone.
