Hey all in iOS26.1 i seem to be getting a bunch of Constraint errors when setting the rightBarButtonItem leftBarButtonItem.
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:0x6000021a2a30 h=--& v=--& _TtCC5UIKit19NavigationButtonBar15ItemWrapperView:0x13d84c080.width == 0 (active)>", "<NSLayoutConstraint:0x6000021a1cc0 _TtCC5UIKit19NavigationButtonBar15ItemWrapperView:0x13d84c080.leading == _UIButtonBarButton:0x106cd3ed0.leading (active)>", "<NSLayoutConstraint:0x6000021a1d10 H:[_UIButtonBarButton:0x106cd3ed0]-(0)-| (active, names: '|':_TtCC5UIKit19NavigationButtonBar15ItemWrapperView:0x13d84c080 )>", "<NSLayoutConstraint:0x6000021a19f0 'IB_Leading_Leading' H:|-(2)-[_UIModernBarButton:0x106cc80b0] (active, names: '|':_UIButtonBarButton:0x106cd3ed0 )>", "<NSLayoutConstraint:0x6000021a1a40 'IB_Trailing_Trailing' H:[_UIModernBarButton:0x106cc80b0]-(2)-| (active, names: '|':_UIButtonBarButton:0x106cd3ed0 )>" )
Will attempt to recover by breaking constraint <NSLayoutConstraint:0x6000021a1a40 'IB_Trailing_Trailing' H:[_UIModernBarButton:0x106cc80b0]-(2)-| (active, names: '|':_UIButtonBarButton:0x106cd3ed0 )>
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.
Curious if im setting something wrong, or maybe i can just ignore these (granted they are annoying in my logs) This wasnt happening in iOS 26.0
