Answer 1

Go to your system activity monitor, search for simulator, double click on it, then quit ==> then fore quit.

It should work afterwards. Don't know why it happens, but it's not the first time, happens on and off.

Thanks, this worked for me. In my case I have a script running that calls xcrun simctl create and if the script exits before deleting this simulator instance, the process hangs. – Twink

Answer 2

For this, just follow these steps, About this Mac > more info > general > storage > developer Click on the information icon. then delete the Xcode cache, then restart the simulator. All will work fine.
