I'm trying to distribute an app for testing; it works fine on Xcode on my Mac. However, when I submit the archive to the App Store, after it finishes the upload process I receive the following error:
ERROR ITMS-90680: "The binary you uploaded was invalid."
An unknown error occurred.
I've tried quitting and restarting Xcode, cleaning my project, and rebuilding the archive...but I continue to receive this error. It's so vague I imagine I'll need Apple to get involved to help...
Xcode Version 9.3 (9E145)
MacOS High Sierra 10.13.4
