Getting “Cannot verify client. (3000)” when trying to upload archive from Xcode to itunesConnect

Question

Just updated to Xcode 7.1 and getting this error. Was able to upload fine using 7.0.1

Answer 1

Exporting the app as an .ipa and uploading via Application Loader 3.0 worked for me. (Restarting xcode, cleaning, and re-archiving did not.)
