Try to have scrollview inside stackview
But when i try to scroll it, it's not working. Label is already more than enough to make it scrollable
Is there any missing constarint ? Main view is in freeform already
CodePudding user response：
Try adding height constraints to the scroll view as it appears that you only have a leading and trailing constraint. You could either try a fixed height size or anchor the top and bottom. Also, your content view should not be anchored to the scroll view. Instead make it have an equal width to the scroll view and then let the height be dictated by the height of the label.

You have some confusing constraints there...
Here is what you want:

<mutableString key="text">There are many variations of passages of Lorem Ipsum available, but the majority have suffered alteration in some form, by injected humour, or randomised words which don't look even slightly believable. If you are going to use a passage of Lorem Ipsum, you need to be sure there isn't anything embarrassing hidden in the middle of text. All the Lorem Ipsum generators on the Internet tend to repeat predefined chunks as necessary, making this the first true generator on the Internet. It uses a dictionary of over 200 Latin words, combined with a handful of model sentence structures, to generate Lorem Ipsum which looks reasonable. The generated Lorem Ipsum is therefore always free from repetition, injected humour, or non-characteristic words etc.</mutableString>
