+    description: |
+        This property is available on devices that support 3D Touch. Default value is `false`.
+
+        If you set this value to `true` for a web view, users (with devices that support 3D Touch) 
+        can preview link destinations, and can preview detected data such as addresses, by pressing on links. 
+        Such previews are known to users as peeks. If a user presses deeper, the preview navigates (or pops, 
+        in user terminology) to the destination. Because pop navigation switches the user from your app to 
+        Safari, it is opt-in, by way of this property, rather default behavior for this class.
