title: Set sort order for UIStackView
body: <p>Is it possible to set a sort order for a <code>UIStackView</code>? For example, I want to sort it by time. Each subview has a <code>time</code> property which is just an <code>Int</code>.</p>
  
  <p>I know you can sort a <code>UITableView</code> by sorting the array and then refreshing the table but <code>UIStackView</code> doesn't have delegates and data sources like that so I don't know how to go about this. It just seems to go by the order you add the subviews in which makes it challenging to add a view in the middle without removing everything first.</p>
