How do I rewrite the code snippet according to this; Setter for 'statusBarStyle' was deprecated in iOS 9.0: Use -[UIViewController preferredStatusBarStyle]
func application(_ application: UIApplication,
didFinishLaunchingWithOptions launchOptions:
[UIApplicationLaunchOptionsKey: Any]?) -> Bool {
FirebaseApp.configure()
UIApplication.shared.statusBarStyle = .lightContent
return true
}
