When trying to test on a plugged in device, I received this error in xcode:
"No provisioning profiles with a valid signing identity (i.e. certificate and private key pair) matching my bundle identifier"
my image is not showing up (😕), here is a link:

Which version Xcode?
Have you ever been able to build to that device?
At any point did Xcode offer to 'fix' a code signing issue?
