Collision Detection in SpriteKit + Swift. Handling collision detection (contact response, in particular) in SpriteKit can be a bit tricky, because the API doesn’t guarantee the order in which objects will appear in the collision callback. Actually overlapping bodies is not a behavior physics engines try to model or have incorporated into their design as a feature - the observed behavior is merely a side-effect, and possibly heavily influenced by the body's parameters (definitely by "bullet" or "continuous" collision detection, usesPreciseCollisionDetection in Sprite Kit terms).
