I have a UIViewController wherein I set nav items, basically the title and the rightBarButtonItem. I use a SF Symbol for the image. The code is extremely simple. Here it is.
func setupNavItem() {
self.navigationItem.title = "Problem in This View"
let helpImage = UIImage(systemName: "questionmark.circle")
let rightBarItem = UIBarButtonItem(image: helpImage, style: .plain, target: self, action: #selector(showHideHelp))
navigationItem.rightBarButtonItem = rightBarItem
}
When I navigate into this view, all heck breaks loose with the constraints. What gives? I'm using Xcode Version 14.0 beta 3 (14A5270f). See the constraint info below.
2022-07-18 16:58:59.998394-0400 NavBarItemExample[28793:996095] [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.
"<NSLayoutConstraint:0x600000a79810 UIImageView:0x136d28790.width <= _UIModernBarButton:0x136d274b0.width (active)>",
"<NSLayoutConstraint:0x600000a7af80 '_UITemporaryLayoutWidth' _UIButtonBarButton:0x136d27280.width == 0 (active)>",
"<NSLayoutConstraint:0x600000a793b0 'IB_Leading_Leading' H:|-(>=11)-[_UIModernBarButton:0x136d274b0] (active, names: '|':_UIButtonBarButton:0x136d27280 )>",
"<NSLayoutConstraint:0x600000a79400 'IB_Trailing_Trailing' H:[_UIModernBarButton:0x136d274b0]-(8)-| (active, names: '|':_UIButtonBarButton:0x136d27280 )>"
)
Will attempt to recover by breaking constraint
<NSLayoutConstraint:0x600000a79810 UIImageView:0x136d28790.width <= _UIModernBarButton:0x136d274b0.width (active)>
Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger.
