    Like the poster, I hit this hideously annoying issue. Likewise, clearing, restarting Xcode, rebooting and the issue persisted. Could not run ANY app from Xcode. Some older references to the same issue, hinted at errant, unterminated processes. Doing a ps -ef showed a large number of processes running (not wholly unexpected). Being suspicious of some process (yes, I am looking at you goolge chrome helper) I rebooted AND unchecked the "reopen windows" option, which I normally use. The number of running processes dropped significantly and Xcode was back to normal. So, I cannot identify any root cause, but this was the solution for me.

    Got this as well – try closing Xcode, Simulator (make sure not running in background) and Terminal (which will show the crash) – then open Terminal and sudo xcode-select -s /Library/Developer/CommandLineTools

    Select an iPhone type in simulator when this runs (mine was cleared)
