Error shutting down simulator

Question

In xcrun simctl documentation there is an entry:

xcrun simctl shutdown booted - Shutdown a device

Bun when I call it from command line, the simulator is not actually shut down but is freezed instead.

How this could be solved?

The only workaround I found is to kill the simulator by its Process ID.

killall "Simluator"

Simulator.app predates CoreSimulator and still assumes that it owns the entire boot lifecycle. You should only use 'simctl shutdown' for devices that you booted via 'simctl boot'.

Could you give me an example how to properly launch Simulator using `simctl boot`? – Andrii Abramov Mar 02 '17 at 13:33

Simulator.app will only work correctly with devices where it owns the lifecycle; we do not currently support mixing simctl boot / simctl shutdown and Simulator.app. Most other simctl commands work with a device started by Simulator.app. – russbishop Mar 05 '17 at 02:10
