UIScrollView not scrolling in Swift

Question

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!         


        

Answer 1

The problem could be that your scrollView doesn't know its contentSize like stated above, but the fix is easier than what the above answers are. Like Carlos said but I will elaborate more. If you want your scrollView to scroll vertically(up & down), make your contentView which is in the hierarchy of the scrollView equal width to the ViewController and give it a height constraint that works for your project i.e. 700. For the opposite(horizontally) make the height equal to the ViewController and the width some big number that works for your project.
