In my situation, I connect my iPhone to the Mac and live preview on the real device. When it comes to the same problem, the HumanReadableSwiftError, everything will be OK after rebooting the iPhone. If I change another iPhone to test, it works as well.

Apparently, 21A5248v > 21A5248u. Just a mistake between u and v? BTW, I can not to pair my iPhone with Xcode for this sake either.
