Hi , I have assignment in swift language (swift 3 and the answers should be with Xcode 8) Create a custom UIView that will draw a coordinate system plain with x-axis and y-axis. then Modify your UIView / When you tap the scrren, the view will redraw the coordinate plain with origin (0,0) equal to my tap position / When you pan and drag you finger, the view will redraw such that it will follow my finger movement. / When you pinch the screen, the view will change its scale until sertine point and then it redraw the normal scale but it will change the values of x and y labels to represent the scale wanted. [without useing scaler or etc..]
