title: How to add leading padding to view added inside an UIStackView
body: <p>This is my setup: I have an <code>UIScrollView</code> with leading,top, trialing edge set to 0. Inside this I add an <code>UIStackView</code> with this constraints:</p>
  
  <pre><code>stackView.centerYAnchor.constraintEqualToAnchor(selectedContactsScrollView.centerYAnchor).active = true  
  stackView.leadingAnchor.constraintEqualToAnchor(selectedContactsScrollView.leadingAnchor).active = true
  </code></pre>
  
  <p>Inside the stack view I add some views.<br>
  My issue is that because of the constraints the first view added to stack view will also have leading edge = 0. </p>
  
  <p>What are the ways that I could add some padding to the first view ? Without adjusting the scroll view constraints.</p>
