Xcode 11 Simulator error, launchd failed to respond

issue happened after updated to Xcode 11 beta, below steps works for me:

step1

reboot Mac, keep holding ‘Command + R’ until recovery mode, then open ‘Terminal’ input :

csrutil disable

this action will disable the SIP

step2

reboot Mac again from recovery mode, remove ‘/private/tmp’ file, open ‘Terminal’ input :

sudo mkdir /private/tmp
sudo chmod 1777/private/tmp

(may require your login password)

then cd to your current user folder, input:

sudo chmod 1777 /tmp

step3

reopen Xcode, simulator back to normal.

step4

reboot Mac again keep holding ‘ Command + R ‘ into recovery mode, open ‘Terminal’ input:

csrutil enable
