Xcode 11 Unable to Boot Simulator Diehard

Xcode on my Macs had a persistent problem after updating to Xcode 10: the simulators wouldn’t work anymore. Lucky me, I was busy with AWS and Kubernetes projects… Updating to Xcode 11 didn’t fix anything. Searching the web didn’t help a ton, since there seem to be many similar problems and simpler solutions, that unfortunately didn’t help at all:

The solution was to run the following command to reset the developer’s path:

sudo xcode-select --reset

Not sure if the reboot I did after that was actually necessary, but I did it anyway.

Moreover, while the installation of Xcode 11 went smoothly the update to 11.1 failed multiple times. Had to delete Xcode and reinstall cleanly. Now everything runs.
