Remote Simulator to Windows
option is not exists in Tools / Options / Xamarin / IOS Settings.
Its seen like this :
What I have done so far :
Check for Visual Studio updates. I had the same problem and I solved it updating Visual Studio.
I hope it works.
Let your voice be heard if you feel iOS Simulator should be included in other levels of VS.

It will work only on enterprise

Remoted iOS Simulator requires a Visual Studio Enterprise license
it will also work in Visual Studio Community 2017, Enterprise is not necessary. Just Go to tools>Extentions and Updates and update your VS. Then you should be able to see "Remote Simulator to Windows" in tools > option > Xamarin > iOS Settings. Enjoy...
