Swift - StackView in ScrollView doesn't scroll

Question

I am trying to make a scrollable stack view inside a scrollview but it doesn't work.

I have built a structure like this:

If you can't see the image, this is the structure:
UIScrollView constrained to superview in all 4 directions
UIStackView (constrained to scrollview in all 4 directions + equal width)
Image Collection View (not constrained)
UIStackView (not constrained)
Stack of Labels (not constrained)

It doesn't scroll, can anyone see what I am missing?

Answer 1

You should set ContentView in your ScrollView with constraints like:

ScrollView's Constraints:

• Leading to superView
• Trailing to superView
• Top to superView

• Bottom to superView

  These constraint's constants are 0

ContentView's Constraints:

• Leading to superView
• Trailing to superView
• Top to superView

• Bottom to superView

• Equal height to ViewController's View (which is in the top of the view hierarchy)

• Equal width to ViewController's View 

  Note: You should set ContentView's height constraint's priority to 700 etc. (lower than default high value)

Attention:

Your stackViews and collectionView must have height for scrollable.

I hope it is works.

Enjoy.
