How do I remove redundant iOS simulator entries from Xcode?

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

XCode > Window > Devices :

Then use the delete key or click the gear icon to remove simulators.
