What XCode is complaining here is that you need to register the devices that you want the archive to run on! Or, it can be an expired license causing the trouble.
Note: Check in Keychain for any expired licenses. Go to View -> Show Expired Licenses. And, remove any or all of the expired licenses in System, Root, and any other categories. Mainly its the WWDC License causing the hassle.
Remove your iOS Development and Provisioning License(s).
Now, after removing all the licenses, add back your Provisioning profile, and the developer profile license. That should do it.
Start a clean build, and archive now. This should accept the archive. Do not forget to register a new device UDID in developer.apple.com portal. It is needed for TestFlight.
