Create an iOS app that starts out by asking the user a few question...

import Foundation
import UIKit
class PUIView: UIView {
   
    private var myColor:UIColor = UIColor.yellow
   
    public override func draw(_ rect: CGRect) {
       let h = rect.height
       let w = rect.width
      
      
       let drect = CGRect(x: (w * 0.25), y: (h * 0.25), width: (w * 0.5), height: (h * 0.5))
       let bpath:UIBezierPath = UIBezierPath(rect: drect) // equivalent to bpath.addLineToPoint() etc...
      
       myColor.set() // this is equivalente to myColor.setFill() myColor.setStroke()
       bpath.fill()
      
       print("it ran")
       NSLog("drawRect has updated the view")
    }
   
    public func changeColor(color:UIColor) {
       myColor = color
    }
}
