For compatibility reasons we are holding approvals for components that contain iOS Unified support until Xamarin.iOS 8.6 is officially released. 8.6 is expected to be released next week. Many components with unified support will be released the same day.
Also note that the demo version supports Android only. This is by design. Full version contains also iOS unified, iOS classic, WP81 and a Xamarin Forms control.
Stay tuned !
