如何在不滚动 SwiftUI 的情况下显示整个列表

Question

Is there a way to make a List be of height that matches its content automatically?

I have a list that will show a number of items (I don't know in advance how many). By default, when I create the list, it doesn't get enough height, instead it shows 1-3 items and scrolls to show more. I would like to disable the scrolling behaviour.

I tried to hardcode frame height to some large value that I'm certain will fit all the items, but this isn't ideal. I can also calculate the frame height from itemHeight * numItems (if I set all the items to specified height themselves), but in my case the items can have varying heights.

Maybe there's a simpler solution for that?

I looked in the documentation, tried also.fixedSize(), different list styles etc. Those didn't work for me.

You should use a VStack instead of a List . This will get rid of the scrolling behavior, but will still give vertically organized cells. You can still use ForEach inside if that's what you are doing inside List .
