Steps to Reproduce:
Can’t reproduce, but I think this is what happend:
* connect a locked iOS Device to a Mac
* keep Xcode running in the background
* wait

Expected Results:
no crash

Actual Results:
Crash after a while

Regression:
Haven’t seen this crash with older Xcode versions

Notes:
The iOS device was connected for a while already before it crashed
