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). Setting Up Physics Bodies SpriteKit gives us a collection of physics bodies we can use to represent our nodes in space: circles, rectangles, composite shapes, and even pixel-perfect collision detection. physicsBody = [SKPhysicsBody bodyWithRectangleOfSize:contactSize]; So my main question is: why is the contactTest not reporting anything?
