title: AutoLayout and Embedded stackview constraint conflicts
body: <p>hoping someone can point me in the right direction here.</p>
  
  <p>I have a layout I'm trying to build with a vertical stackview.  Stackview is pinned at the left, top and right edges of view at 0.  I have a horizontal stackview inside which has 3 images all 30x30 that I want left aligned.  (Not spaced out across horizontal stack.)</p>
  
  <p>XCode continues to give me conflicting constraints errors here.  I believe its because it wants my stackview to be at 100% of outer vertical stack view width.  I can add in a random view that stretches and it fixes the problem, but this seems VERY clunky.</p>
  
  <p>What's the best approach for this?</p>
