Here are Easy steps to integrate scrollview in iOS storyboard

Steps:

1. Add ScrollView to the ViewController XIB or storyboard
2. Add constraints to all four corners
3. Add a UIView inside the UIScrollview and add constraints with the scrollView to all four corners.
4. Set equal width between the UIView and the scrollView.
5. Add height to the UIView (If the height is greater than the height of the device, It automatically becomes scrollable).
