While there are various ways that we could address those problems (for example by using a technique similar to the one we used to make multiple views have the same width or height in this Q&A article), the question is really whether measuring the available space is really a good approach when it comes to determining the orientation of our dynamic stacks. The result of that is that animations will be much smoother, for example when switching device orientations, and were also likely to get a small performance boost when performing such changes as well (since SwiftUI always performs best when its view hierarchies are as static as possible).

The example in line 6 would align all the elements in the VStack to the left of the VStack view. Use the regular VStack when you have a small number of subviews or don't want the delayed rendering behavior of the "lazy" version..
