If IsSwipingEnabled is set to true and data is  dynamically added to SlideView control when the user swipes through the items, the content is not displayed and the control becomes non-responsive.  The same approach works properly if the user uses the slide buttons to navigate between the items.

SlideView item does not update after navigation between pages

After an item is removed from the ItemsSource, if you swipe, the indicators are not properly updated.
