My UIScrollView won\'t scroll down. I don\'t know why. I already followed Apple documentation regarding to this issue.
@IBOutlet weak var scroller: UIScrollView!
If you use AutoLayout,
Set content size in viewdidAppear which works for me.
override func viewDidAppear(_ animated: Bool) {
scrollView.contentSize = CGSize(width: UIScreen.main.bounds.width, height: UIScreen.main.bounds.height+300) }
