Answer: add stackview height constraint
(or add stack view content resistence and content hugging priorities higher than those of your UIImageView)

Explanation: Since you are using storyboard's Interface builder (IB) for creating constraints, as opposed to pure code. The IB uses feature of auto-constraints, which basically means that the IB can figure itself the layout and constraints based on what is displayed in your storyboard. The UIStackView is using some dynamic resizing (so that elements within stackview are properly layed out) and it is always good idea to give it size constraints, or at least size constraints to elements inside UIStackView , otherwise it might decide that every element has size of CGSize(height:0,width:0) You can also make priorities of your UIStackView higher than those of your UIImageView so that IB would prioritize the size of your stackview's constraints to those of your imageView
