I'm pretty new to xamarin, tried to run a sample application (IOS). But Visual Studio says: `"Please select a valid device before running the application"`

I know on the IOS toolbar, there should be option to select which device to simulate (list of supported IOS devices like iphone 6, 5s etc), but I don't get that.

EDIT: To be more precise, TARGET IOS Device not shown on IOS Tool bar
