Hi @goodboygb1 you can collect your viewed story using snapIndex - didSet method create your function in StoryPreviewProtocol and whenever the SnapMovementDirectionState.Forward direction called, you can throw your viewedSnap to your own viewcontroller. Story can have multiple snaps. snap mime type can be a image/Video/etc. How ever you can track which snap already viewed by which story. both you can capture with help of this!!!
