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!
Do not give fix height to scroll view and always give top of first subview to scrollview and bottom of last subview to scrollview. By this way scroll view will automatically grow as per the size of contained subviews. No need to give contentSize to the scrollview.It will work for small as well as large size iPhone.
