Answer 1

Problem is in constraints. Follow these steps:

Add a container view in scroll view and set top, bottom, leading and trailing constraints of container view with scroll view. Do not set height of this container view. add other views in this container view. Height of container view will adjusted according to sub views of container view. Height of sub views of container view should not set proportional to container view, it should set proportional to scroll view.

Also make sure you have set the top and bottom of container view to its sub view
