title: Xcode: Stack View Move to next line if screen is too small
body: <p>Using Stack View, I want to get 3 items next to each other, which I achieved:

  <p>However, what I am looking to do is if the screen is too small to fit everything nicely in, then to move the block to the next line such as:
  <a href="https://i.stack.imgur.com/TH9P4m.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/TH9P4m.png" alt="enter image description here"></a></p>
  
  <p>Should I not be using Stack View for this? </p>
