I observed these issues sometimes when my mac is not connected to the internet. So here is a solutions list one of them may solve your problem.

  1. Check if you have an internet connection running in your mac.
  2. Restart the simulator.
  3. Restart mac if required.

Hope this will help you. Thanks

In this case, launchd is crashing when trying to launch.

This could be as a result of deleting the /private/tmp folder.

To resolve this, I typed the following commands on my terminal: 

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