I have seen endless confusion with anything even remotely iconic. People swiping in the "obviously" opposite direction and getting frustrated, never swiping in the right direction. Telling people to "swipe" ends up going nowhere. We have no iconography. We have no language. It must be representative to actually get people to understand what you want them to do. Iconography can come later, when people actually understand that swiping is a thing you do with your finger. This is at least pretty clear.
