After updating from iOS 26 to iOS 26.1, all my transparent system elements (i.e. UITabBar, UIBarButtonItem) started rendering with a dark background tint. In iOS 26 the same configuration looked fully transparent / glassy. The strange part is that the tint only appears in normal UIViewControllers. In UITableViewController the tab bar still looks correct and transparent, even on iOS 26.1. I am using the same appearance code as before: func setupTabBarAppearance() { guard let tabBar = tabBarController?.tabBar else { return } if #available(iOS 26.0, *) { let appearance = UITabBarAppearance() appearance.configureWithTransparentBackground() appearance.backgroundColor = .clear appearance.backgroundEffect = nil appearance.shadowColor = .clear tabBar.standardAppearance = appearance tabBar.scrollEdgeAppearance = appearance tabBar.isTranslucent = true tabBar.backgroundColor = .clear tabBar.barTintColor = .clear } else { tabBar.isTranslucent = true tabBar.backgroundImage = UIImage() tabBar.shadowImage = UIImage() tabBar.backgroundColor = .clear } } I tried removing backgroundEffect, forcing .clear colors, using configureWithDefaultBackground, changing edgesForExtendedLayout, extendedLayoutIncludesOpaqueBars, etc. I noticed that if I change Liquid Glass in iOS 26 settings from Clear to Tinted, then I get a black tint everywhere and the interface becomes consistent, but not the way I want. Nothing removes the new dark tint in iOS 26.1. Is this an intentional change in iOS 26.1, a bug, or is there a new way to make the tab bar fully transparent again?
