Discussion
A point in the SpriteKit node’s 2D viewport coordinate space can refer to any point along a line segment in the 3D SceneKit coordinate space. Hit-testing is the process of finding elements of a scene located along this line segment. For example, you can use this method to find the geometry corresponding to a touch event.
