This stuff is pre-iOS 13 appearance customization. Using the new stuff will disable it. > > let navBar = self.navigationController!.navigationBar > let standardAppearance = UINavigationBarAppearance() > standardAppearance.configureWithOpaqueBackground() > standardAppearance.backgroundImage = UIImage() > > navBar.standardAppearance = standardAppearance > navBar.scrollEdgeAppearance = standardAppearance With iOS 13 the navigation bar now has multiple appearance states. The scrollEdgeAppearance is when your bar is at the edge of a scroll view (top for a navigation bar, bottom for tab & toolbar). This configures the bar to use the same appearance state (in this case, a solid color background, using UIColor.systemBackgroundColor). In context the setting of backgroundImage doesn’t do anything (it defaults to nil and empty images have identical behavior). By setting standardAppearance == scrollEdgeAppearance it in turn disables the “bar becomes transparent at the top” behavior introduced for large titles in iOS 13 and extended to all bar in iOS 15. > > > Thanks again David.
