The task is as follows: on one view there are four rectangles with the same shape and size. It is necessary to write a form for the test where three of them conditionally contain answers to the question and must be dragged into the fourth, depending on the chosen answer, further behavior will vary).
Question: How can I implement this behavior without engines? Is it also possible without OpenGL, Core Animation-Core Graphics?
I would be grateful for any constructive suggestions!
