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.
(
"<NSLayoutConstraint:0x15df2750 V:[UIView:0x15deddf0(>=44)]>",
"<NSLayoutConstraint:0x15df2570 UIView:0x15deddf0.height == UIView:0x15dedcd0.height>",
"<NSLayoutConstraint:0x15df3160 _UIAlertControllerView:0x15ded690.height == UIView:0x15dedcd0.height>",
"<NSLayoutConstraint:0x17126e40 _UIAlertControllerView:0x15ded690.height == UIView:0x15deb540.height>",
"<NSLayoutConstraint:0x15e030e0 'UIView-Encapsulated-Layout-Height' V:[UIView:0x15deb540(21)]>"
)
Will attempt to recover by breaking constraint
<NSLayoutConstraint:0x15df2750 V:[UIView:0x15deddf0(>=44)]>
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.
