Unable to Boot Device in Current State: Booted?

This error usually occurs when your device has already booted or when there was an issue during the boot process. This error message might appear on a variety of devices, such as computers, cell phones, and other electronic gadgets. But most commonly on iOS and Android devices when running automation tests with tools like Appium. In the case of iOS devices, this command can quickly fix the issue: Disable the autostart of the last opened device by default in preferences appium/appium-ios-simulator#320. Also, this should be noted that this error can also be because of the outdated version of Appium or any other tool you might be using. 

Also, there are other ways to deal with this issue as well. It is possible that this problem can be a side effect of you having deleted the ~/Library/Developer/CoreSimulator/Devices directory when CoreSimulatorService was running. Your iOS device was probably in a state where it didn't have its data directory during execution. So, because of that it is failing to boot and this message is being prompted. It is suggested to run 'xcrun small erase [UDID]' where you will get the UDID by checking the output of the 'xcrun small list'.

It is strongly advised that one should never just delete the CoreSimulator/Devices directory yourself otherwise problems like these are likely to happen. If a user or tester has to delete the directory because of some reason, then make sure that the service is not running while you delete it. You can do that by running these commands: 

# Quit,, etc
sudo killall -9 rm -rf ~/Library/*/CoreSimulator.
