How to shutdown gracefully the simulators for headless testing?

[atineoSE]

I am trying the headless testing with the boot-simulators command. It looks like new simulator devices are being created and booted in the provided folder (/tmp/test-simulators in your example).

How can I gracefully shutdown (and possibly delete) the newly created simulator devices after being done with the tests?

This should work: xcrun simctl --set /tmp/test-simulators shutdown all

That worked, thanks!

hi although i use this command i get the error below when i want to run the tests again. Do you have any other suggestion? Error Domain=com.facebook.FBSimulatorControl Code=0 "Failed to boot Simulator with options { env = { "SIMULATOR_IS_HEADLESS" = 1; }; persist = 1; "register-head-services" = 1; }" UserInfo={NSLocalizedDescription=Failed to boot Simulator with options { env = { "SIMULATOR_IS_HEADLESS" = 1; }; persist = 1; "register-head-services" = 1; }, NSUnderlyingError=0x7fdf7c469950 {Error Domain=com.apple.CoreSimulator.SimError Code=163 "Unable to boot device because it cannot be located on disk."

@okanerdogan84 can you post the exact command sequence you follow?

Here is a sample of mine:

killall -9 com.apple.CoreSimulator.CoreSimulatorService worked for me. Thanks
