1K views and no answers. Surely some developers have solved it. But, keeping it a secret so that only their app can download media LOL! I just got this rejection as well. Gonna try something and if it works will reply here.

Same here. mine a GIF downloader from twitter, got rejected for being too simple. granted there are only 4 button in the main UI - 1 to download GIF. 1 to show info. 1 to share gif, 1 to adjust gif animation. but this is what utility apps are! i tried to reason with the reviewer, but no still rejected. so yeah i am bringing it to android instead. fucking apple.
