Trying to build and run on both my iPad Pro 10.5 and iPhone X (both running the 10.12 beta) from Xcode 10, I get this error, with the additional info:
"Please try rebooting and reconnecting the device. (0xE8000022)."
Rebooting and reconnecting does not help. Note that the app installs and I can start it by hand, but not from inside of Xcode, which is obviously frustrating.
Anyone else seeing this? Any sugs on how to work around it for now?
For me, I've just had this same error message after updating iOS to the most recent version (in my case 13.3), and had connected it to Xcode for the first time since the upgrade. When looking at Devices under 'Devices and Simulators' I could see the yellow 'preparing for development' banner.
Once that had completed and the banner had disappeared, build and running from Xcode on my iPhone was working fine.
