title: What is the best way to resolve the error "Unable to simultaneously satisfy constraints"?
body: <p>I imagine most projects don't have just one or two stack views with constraints, so.... 
  How can I use the information provided in this error report to trace down exactly which constraint(s) in my project is problematic? In a project with potentially hundreds of constraints, how can I know which 2 constraints are being problematic in this case? </p>
  
  <pre><code>2020-03-22 14:31:59.690493-0400 Splittr[39203:4533416] [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. 
  (
      "&lt;NSLayoutConstraint:0x600001eff0c0 H:|-(4)-[UIStackView:0x7fa5ec678e30]   (active, names: '|':UIStackView:0x7fa5ec601960 )&gt;",
      "&lt;NSLayoutConstraint:0x600001ec8500 'UISV-canvas-connection' UIStackView:0x7fa5ec601960.leading == UIStackView:0x7fa5ec678e30.leading   (active)&gt;"
  )
  
  Will attempt to recover by breaking constraint 
  &lt;NSLayoutConstraint:0x600001ec8500 'UISV-canvas-connection' UIStackView:0x7fa5ec601960.leading == UIStackView:0x7fa5ec678e30.leading   (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.
