Hi, When I run the following code in application(_ :didFinishLaunchingWithOptions) in iOS 15, the bar color turns transparent (thus, showing the black background underneath), while the same code works fine in iOS 14.5: UINavigationBar.appearance().isTranslucent = false UINavigationBar.appearance().barTintColor = .red Here's the screenshots of Simulators running iOS 14.5 and iOS 15: I'm using Xcode 13 on macOS Big Sur 11.4. Thanks!
