    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:0x600002184500 'assistantHeight' SystemInputAssistantView.height == 45   (active, names: SystemInputAssistantView:0x109133490 )>",
        "<NSLayoutConstraint:0x60000217aad0 'assistantView.bottom' SystemInputAssistantView.bottom == _UIKBCompatInputView:0x109133be0.top   (active, names: SystemInputAssistantView:0x109133490 )>",
        "<NSLayoutConstraint:0x60000217b8e0 'assistantView.top' V:[_UIRemoteKeyboardPlaceholderView:0x1091df4f0]-(0)-[SystemInputAssistantView]   (active, names: SystemInputAssistantView:0x109133490 )>",
        "<NSLayoutConstraint:0x60000218ac10 'inputView.top' V:[_UIRemoteKeyboardPlaceholderView:0x1091df4f0]-(0)-[_UIKBCompatInputView:0x109133be0]   (active)>"
    )
    
    Will attempt to recover by breaking constraint 
    <NSLayoutConstraint:0x60000217b8e0 'assistantView.top' V:[_UIRemoteKeyboardPlaceholderView:0x1091df4f0]-(0)-[SystemInputAssistantView]   (active, names: SystemInputAssistantView:0x109133490 )>
    
    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.
