Swipe Widget

This sample demonstrates how to use a Swipe widget to compare two different TileLayers from the 2018 Kilauea eruption. The Swipe widget allows users to view collections of layers simultaneously by placing a divider and handle in the view to display selected parts of a layer or layers. This widget currently works with all layers except GroupLayers.
