The outlet shanghaiImage is my background I would like to add a gradient on top of this marty like: transparent (top) to black (bottom). Thanks for the help :) Here is my code in Swift 3. This part is fine : import UIKit class ViewController: UIViewController { @IBOutlet weak var shanghaiImage: UIImageView! // beginning index var
