The interaction object that triggered the preview.
The configuration object associated with the current interaction.
An object containing the source view and configuration parameters for the animation.
UIKit calls this method before an interaction begins, to give you an opportunity to supply a custom source view for the presentation animations. If you didn't provide a preview handler block in the
configuration data, UIKit displays the specified view in the preview interface.
