title: Constraints breaking for iPhone 6+ with dynamically sizing cells
body: <p>I have a UITableViewCell setup like below:</p>
  
  <p><a href="https://i.stack.imgur.com/dRWTQ.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/dRWTQ.png" alt="enter image description here"></a></p>
  
  <p>An image with the date, a divider line (UIView) and a text field. Constraints are set like so:</p>
  
  <p>Image: pin top top, trailing and leading edges, aspect ratio enabled.</p>
  
  <p>Date: pin to top (image), leading, fixed height and width</p>
  
  <p>Divider: pin to top (date), trailing, leading, fixed height</p>
  
  <p>Text: pin to top (divider), bottom, trailing, leading, fixed height</p>
  
  <p>I want the cells to dynamically change size depending on the size of the content so in my UITableViewController I have:</p>
  
  <pre><code>tableView.estimatedRowHeight = 254
  tableView.rowHeight = UITableViewAutomaticDimension
  </code></pre>
  
  <p>I have tested it for iPhone4, iPhone5 and iPhone6. It all works fine. However for iPhone6+ I get the error in the console: 
  <em>Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger.
  The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in  may also be helpful.</em></p>
  
  <p>It looks fine in the simulator though. What could I be doing wrong here? If the cells and views size up correctly for the other phone sizes then why would it break for the 6+?</p>
  
  <p>Any pointers on this would be great!</p>
