Question

I wanna add scroll view in my project but in swift 5 I can't add it I tried many ways

@IBOutlet weak var scrollView: UIScrollView! 
@IBOutlet weak var imageViewBottomConstraint: NSLayoutConstraint!
@IBOutlet weak var imageViewLeadingConstraint: NSLayoutConstraint!
@IBOutlet weak var imageViewTopConstraint: NSLayoutConstraint!
@IBOutlet weak var imageViewTrailingConstraint: NSLayoutConstraint!

Answer 1

1.Add scrollView(1) in storyboard, add needed constraint to top/bottom/trailing/leading.

2.Then uncheck "Content Layout Guides" in Size inspector section for your scrollView.

3.Then you need to put into your scrollView new UIView(2), its constraints are for top/bottom/trailing/leading to superView(1) and equal width to superView(1).

4.Then the height of your view(2) you can add as constraint or you can add the content, which will give the height to your view(2).

Example with the height setted

Example with the content, which give the height to your view(2)

Answer 2

It works 100% when I Disabling the content layout guides in properties

Answer 3

If you use interface builder first of all add your scroll view and set scroll view constraint (top, bottom, leading and trailing) as (0,0,0,0). View hierarchy must be like this view -> scroll view -> view(content view). Again add constraints for your content view. Content view must have equal width and equal height with parent view (Scroll View). Control drag from content view to scroll view in Document Outline
