How do I remove all these extra simulators from my Xcode menu?
回答1:
XCode > Window > Devices :
Then use the delete key or click the gear icon to remove simulators.
回答2:
If you want to do this quickly I'd recommend fastlane tools you can reset simulators with one line
fastlane snapshot reset_simulators
install fastlane tools
sudo gem install fastlane
Make sure, you have the latest version of the Xcode command line tools installed:
xcode-select --install
(https://docs.fastlane.tools/actions/capture_ios_screenshots#completely-reset-all-simulators)
And the command is
fastlane snapshot reset_simulators

You don't need to delete the Simulators you don't want to see on the run destinations drop-down menu. On Xcode 9 you can just hide the ones that you don't need.
Go to Window > Devices and Simulators (ShiftCmd2)
Pick the Simulator from the left and untick 'Show as run destination' as seen below:

You can remove devices easily now in XCode 9, but use the Simulator toolbar. With a Simulator running, go to the top bar and go to Hardware -> Device -> Manage Devices then select Simulators. You are presented with the option [Devices | Simulators] So select simulators. Then work your way down the list, and untick the Simulators, and OS versions you don't want. Too easy. When you look in XCode for a Simulator to use, the list will now be much shorter. Removing unwanted Simulators

There is a nice shell script that deletes all simulators and creates a list of new ones for you on GitHub without the need of Fastlane (even though Fastlane is worth to have anyway):
