问题
I am using Xcode 12 with the iOS 13.4 Simulator. On bootup, I get this crash report.
Failed to start launchd sim: could not bind to session, launchd sim may have crashed or quit responding.
What can cause this? It works in Xcode 11 but not in Xcode 12.

So it problem was my project had permissions that it can only run in sudo mode. When I tried to run the simulator in sudo mode, it failed. I had to change the permissions of my project, to be able to run in non sudo mode. When this happened, I could run the iOS simulator perfectly fine.
