Can't upload archive to app store since yesterday
just upload the ipa with Application Loader 2.9.1, even thought the apple tell you that you should upload the ipa with xcode 7.2 or Application Load 3.0.0, but , my solution works welldownload Application Loader 2.9.1
Try thisXcode -> Open Developer Tool -> Application Loader -> Login with AppleID -> Choose your app IPAmay this help you
Another solution that might help is disabling bitcode when submitting the IPA through XCode. Not sure why but this worked for my colleague when he had the same issue. If you want to keep bitcode then Application Loader will work, as pradip kikani pointed out.
