[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. 
	(Note: If you're seeing NSAutoresizingMaskLayoutConstraints that you don't understand, refer to the documentation for the UIView property translatesAutoresizingMaskIntoConstraints) 
(
	<NSAutoresizingMaskLayoutConstraint:0x600001ca32f0 UISearchBar:0x7f8388e4a840.(null) == 2>,
	<NSLayoutConstraint:0x600001ca4c30 UISearchBar:0x7f8388e4a840.left == UIView:0x7f8388e4a6e0.left>,
)

Will attempt to recover by breaking constraint 
<NSLayoutConstraint:0x600001ca4c30 UISearchBar:0x7f8388e4a840.left == UIView:0x7f8388e4a6e0.left>

Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger.
The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in <UIKitCore/UIView.h> may also be helpful.
