Hi Team ,
We are facing the same issue as below, but by using the below method it will fixes the crash ? Does this apple beta release bug ? will this be fixed in the final 16.1 release ?
navigationController?.isNavigationBarHidden = false // App is crashing here, not first time, but when you go-back and push into Navigation again
self.navigationController?.setNavigationBarHidden(false, animated: false) // App is not crashing ,it works well
Fatal Exception:
NSGenericExceptionUnable to activate constraint with anchors <NSLayoutDimension:0x283163980 "_UINavigationBarTitleControl:0x10421e620.height"> and <NSLayoutDimension:0x28317f800 "UILayoutGuide:0x281d12840'TitleViewGuide(0x10424b970)'.height"> because they have no common ancestor. Does the constraint or its anchors reference items in different view hierarchies? That's illegal.
