XCode: Stack view and constraints

Why would I need contraints on elements that live inside my stack view? Is not the idea of the Stack View to stack elements automatically thus making the need of explicit measures to be added?

Well Said. Stackview get its height and width from content size. Sometime we cannot say exactly how much content size a ui element has.

For example if we have an imageview inside stackview and we assign image at runtime. The stackview will grow with the imageview. The question is how much. Well it depends on the size of image. So there we can feel undesired results. So we fix stackview size using predefined constraints.

Also, Stackview need constraints for position. Where to position stackview inside view of viewcontroller. So we need constraints for positioning our stackview.
