Back button not aligned properly in iOS 11

Question

We started working on our project with Xcode 8.3 and it was all fine till iOS 10 but when we run our same app in iOS 11 the back button is not aligned as intended as you see in the image below

But with iOS 10 it's aligned properly

And this what the layout constraint error we are getting

(
"<NSLayoutConstraint:0x600000288200 _UIModernBarButton:0x7f7ef5c87f10.bottom == UILayoutGuide:0x6000005a0380'UIViewLayoutMarginsGuide'.bottom + 64.5   (active)>",
"<NSLayoutConstraint:0x600000287f30 V:[_UIModernBarButton:0x7f7ef5c87f10]-(>=0)-|   (active, names: '|':_UIButtonBarButton:0x7f7ef5c86e60 )>",
"<NSLayoutConstraint:0x600000282030 'UIView-bottomMargin-guide-constraint' V:[UILayoutGuide:0x6000005a0380'UIViewLayoutMarginsGuide']-(16)-|   (active, names: '|':_UIButtonBarButton:0x7f7ef5c86e60 )>"

)

Answer 1

For me it is because I use some tricks like below to hide the title

UIBarButtonItem.appearance().setBackButtonTitlePositionAdjustment(UIOffsetMake(0, -1000), for: .default)

We should not do that, it does not work on iOS 11 and will trigger lots of Auto Layout issue like you post. So check if you have appearance on back button.

If you really want to hide text on the back button, you should do https://stackoverflow.com/a/46889050/1418457
