01. First in Plist set View controller-based status bar appearance to NO
02. Add this code to AppDelegate.swift
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
// Set Status Bar to light colour for ALL ViewControllers
//UIApplication.shared.statusBarStyle = .lightContent
//Set Navigation Bar text to black for ALL ViewControllers
UINavigationBar.appearance().backgroundColor = UIColor.red
UINavigationBar.appearance().tintColor = UIColor.black
return true
}
