let navigationBar = UINavigationBar()
navigationBar.tintColor = .white
navigationBar.standardAppearance = appearance

You are creating a navigation bar, configuring it, and throwing it away. That does nothing for your app. Rewrite meaningfully:

    let appearance = UINavigationBarAppearance()
    appearance.configureWithOpaqueBackground()
    appearance.titleTextAttributes = [.foregroundColor: UIColor.white]
    appearance.backgroundColor = .red
    let proxy = UINavigationBar.appearance()
    proxy.tintColor = .white
    proxy.standardAppearance = appearance
    proxy.scrollEdgeAppearance = appearance

// Apply the configuration option of your choice
appearance.configureWithTransparentBackground()
            
// Create button appearance, with the custom color
let buttonAppearance = UIBarButtonItemAppearance(style: .plain)
buttonAppearance.normal.titleTextAttributes = [.foregroundColor: UIColor.white]

// Apply button appearance
appearance.buttonAppearance = buttonAppearance

// Apply tint to the back arrow "chevron"
UINavigationBar.appearance().tintColor = UIColor.white

// Apply proxy
UINavigationBar.appearance().standardAppearance = appearance

// Perhaps you'd want to set these as well depending on your design:
UINavigationBar.appearance().compactAppearance = appearance
UINavigationBar.appearance().scrollEdgeAppearance = appearance
