Swift-Get screen click coordinates under All objects (Spritekit game development)

for the click response of the object element in the scene, we can process it uniformly within the Touchesbegan () method of the scene.

Skscene in Touchesbegan () is a way to respond to a screen click, where we can first get all the objects under the click, and then filter out the desired object and then call the method of the object.
