We recently noticed these tiny black bugs that seem to have an orangish redish color on there legs all over our wooden swingset and also recently discovered them all over our willow tree as well, I have never seen these bugs before and wonder if they cause any harm

Giant Willow Aphids

Hi Jessica,
You have Giant Willow Aphids,
Tuberolachnus salignus and we verified the identification on BugGuide.  Aphids are considered significant agricultural pests, especially when they are numerous, but any harm they might cause would be to your willow tree, not to you or your swing set, though we imagine they are a bit of a nuisance on the swing set.
