Image slideshow?

Hi, I mocked up something to display a random image from the iCloud Drive in a ListWidget, but it’s not satisfactory how slow iOS updates the widgets. Is there a better way or a workaround to achieve the same result (trigger a draw update)?

I’ve looked into:

  1. Using a timer to re-addImage and re-setWidget. (Does not update the widget)
  2. There doesn’t seem to be an API for binding to swipe actions (i.e. a swipe would change images)
