Each child view occupies a row in the list view. While ScrollView put every child views under one container view, this resembles UIScrollView. It is that wrapper view that we must think of as the frame. You can see that List wrap each TupleView s child view into a row-like structure ( ListCoreCellHost ), which resembles UITableView. Most of the time, when we apply a modifier on a view, a new view is created that is wrapped around the view being modified. Modifiers in SwiftUI do not actually modify views. With LazyVStack, in this example, we can scroll. frame(width: 80, height: 100) VStack(alignment.
