Xamarin.Forms provides an abstracted UI definition of common controls across platforms. This makes design faster since you can simply specify a Button or a Picker without knowing or caring that the actual implementations on iOS are UIButton or UIPickerView (eg: UIDatePicker) or that on Android they are android.widget.Button or android.app.DatePickerDialog. All UIs defined in Xamarin are rendered with OS-native widgets.
