Can I delete unnecessary device simulators of Xcode?

I found that Xcode on my laptop consumes much of its storage, so I am trying to delete unnecessary files in Xcode. There are four directories under Application/Xcode.app/Contents/Developer/Platforms/. I feel that WatchSimulator.platform and AppleTVSimulator.platform are not necessary, because I use Xcode almost only for basic iOS development. I would like to know if I can delete those platforms directories directly?
