SwipeView Swipe Transition Mode on iOS

This iOS platform-specific controls the transition that's used when opening a SwipeView. It's consumed in XAML by setting the SwipeView.SwipeTransitionMode bindable property to a value of the SwipeTransitionMode enumeration:

<ContentPage ...
             xmlns:ios="clr-namespace:Xamarin.Forms.PlatformConfiguration.iOSSpecific;assembly=Xamarin.Forms.Core">
    <StackLayout>
        <SwipeView ios:SwipeView.SwipeTransitionMode="Drag">
            <SwipeView.LeftItems>
                <SwipeItems>
                    <SwipeItem Text="Delete"
                               IconImageSource="delete.png"
                               BackgroundColor="LightPink"
                               Invoked="OnDeleteSwipeItemInvoked" />
                </SwipeItems>
            </SwipeView.LeftItems>
            <!-- Content -->
        </SwipeView>
    </StackLayout>
</ContentPage>

Alternatively, it can be consumed from C# using the fluent API:

using Xamarin.Forms.PlatformConfiguration;
using Xamarin.Forms.PlatformConfiguration.iOSSpecific;
...

SwipeView swipeView = new Xamarin.Forms.SwipeView();
swipeView.On<iOS>().SetSwipeTransitionMode(SwipeTransitionMode.Drag);
// ...

The SwipeView.On<iOS> method specifies that this platform-specific will only run on iOS. The SwipeView.SetSwipeTransitionMode method, in the Xamarin.Forms.PlatformConfiguration.iOSSpecific namespace, is used to control the transition that's used when opening a SwipeView. The SwipeTransitionMode enumeration provides two possible values:

  • Reveal indicates that the swipe items will be revealed as the SwipeView content is swiped, and is the default value of the SwipeView.SwipeTransitionMode property.
  • Drag indicates that the swipe items will be dragged into view as the SwipeView content is swiped.

In addition, the SwipeView.GetSwipeTransitionMode method can be used to return the SwipeTransitionMode that's applied to the SwipeView.

The result is that a specified SwipeTransitionMode value is applied to the SwipeView, which controls the transition that's used when opening the SwipeView:
