I don't think there is a way to do this, but is there a way to detect when 2 SKSpriteNodes intersect with each other, but still allow them to overlap, so they don't actually bounce over each other?
I know I can just have 1 without a physics body, and then write some code to check their co-ordinates, but I thought maybe I might be missing something in Sprite Kit where I could detect this with SK methods.
