Xcode doesn\'t see my dev

Answer 1

I ran into this issue today where Xcode 8.2.1 suddenly decided the connected ipad (ios 10.2) was no longer connected. Unplugged, plugged back in, rebooted my macbook, and tried numerous recommendations above. The thing that fixed the issue for me was shutting down and rebooting the ipad device itself.
