Good evening, this is Bono.

I was creating an iPhone application in Xcode.
I had a problem and couldn't find anything by googling it, so I'm leaving a reminder.

iPhone screen goes dark.


The following symptoms occurred.

  • Xcode cannot run using the selected device." "Busy" is displayed and the application does not start.
  • The iPhone screen remains dark.
  • Siri or vibrate works.


Restart the iPhone using the following method.

Press the Home button and the Power button simultaneously for 10 seconds.

That's it. Whew, I'm finally back.
