I'm seeing an error appear in my debugger log:
Will attempt to recover by breaking constraint
Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger.
The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in <UIKit/UIView.h> may also be helpful.
You'll want to add a
Symbolic Breakpoint. Apple provides an excellent guide on how to do this.
Addbutton in the lower left
Add Symbolic Breakpoint...
Symboljust type in
You can also treat it like any other breakpoint, turning it on and off, adding actions, or log messages.
