XCTests Failing on Physical Device: “Canceling tests due to timeout …”

Question

XCTests are failing with the message: *** Canceling tests due to timeout in Waiting for test process to check in... This just started coming up in the last few days

Answer 1

I wanted to add another solution here for others to check. If your laptop is subject to a strict antivirus, make sure that they have exempted ~/Library/Developer. I was running into this issue because my antivirus was quarantining ~/Library/Developer/CoreSimulator/Devices/......

Hard to run tests if the test process is quarantined.
