I’m able to launch on a mac but once I remove the iOS provisioning profiles and leave just the tvOS profiles I get the same error as you.
So if you haven’t already I would try creating iOS profiles with the same bundle id. I also had to make the project a coded project in order for it to get past a different error.
Another issue I just figured out is you want to open up the Application Loader from Xcode(Xcode->Open Developer Tool->Application Loader) not from the applications folder. I’m getting a couple of errors though that I need to figure out but opening Application Loader that way sees it as an tvOS app and the other does not.
