title: How to find which view is causing 'Unable to simultaneously satisfy constraints'
body: <p>Sometimes I will get a layout issue, but I won't be sure which view is sending it. First I get logs like this</p>
  <pre><code>2020-07-17 18:46:00.243783+0200 your-app[97175:3182603] [LayoutConstraints] Unable to simultaneously satisfy constraints.
      Probably at least one of the constraints in the following list is one you don't want. 
      Try this: 
          (1) look at each constraint and try to figure out which you don't expect; 
          (2) find the code that added the unwanted constraint or constraints and fix it. 
  (
      &quot;&lt;NSLayoutConstraint:0x600003a76d00 UIView:0x7f967ff233d0.width == - 16   (active)&gt;&quot;
  )
  
  Will attempt to recover by breaking constraint 
  &lt;NSLayoutConstraint:0x600003a76d00 UIView:0x7f967ff233d0.width == - 16   (active)&gt;
  
  Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger.
  The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in &lt;UIKitCore/UIView.h&gt; may also be helpful.

  <p>How do I tell which view is causing this?</p>
