ios – Standing bar problem in machine darkish mode

I’m including possibility so as to add possibility for consumer to decide on system/mild/darkish modes.

I’m storing consumer alternative in userdefaults. Beneath is my code in AppDelegate and buyer UINavigationController class.

Challenge is when machine is in darkish mode and consumer has chosen mild mode then standing bar isn’t seen. Equally, if machine is in mild mode however consumer has chosen darkish mode then standing bar isn’t white.

Tried options proven on some posts however not capable of get round.

if let currentUserSelectedInterfaceStyle = userDefaults.string(forKey: "currentUserInterfaceStyle") {
                        
            swap currentUserSelectedInterfaceStyle {
                
                case "mild" :
                    window?.overrideUserInterfaceStyle = UIUserInterfaceStyle.mild
                    
                case "darkish" :
                    window?.overrideUserInterfaceStyle = UIUserInterfaceStyle.darkish
                    
                case "system":
                    window?.overrideUserInterfaceStyle = UIUserInterfaceStyle.unspecified
                    

                default:    
                    window?.overrideUserInterfaceStyle = UIUserInterfaceStyle.unspecified
                    

            }
            
        } else {


            userDefaults.set("mild", forKey: "currentUserInterfaceStyle")
            userDefaults.synchronize()
            
            window?.overrideUserInterfaceStyle =  .mild

        }
}

Customized navigation controller class

is setting statusBarStyle to UIStatusBarStyle.default a problem? However i can not set it to different worth earlier than nav controller is instantiated.

class DarkModeAwareNavigationController: UINavigationController {
                
    var statusBarStyle =  UIStatusBarStyle.default { didSet
        {
            setNeedsStatusBarAppearanceUpdate()

        }

    }
    override var preferredStatusBarStyle: UIStatusBarStyle {
        statusBarStyle

    }
    
    override open var childForStatusBarStyle: UIViewController? {
            return self.topViewController
        }
        
    override init(rootViewController: UIViewController) {
       tremendous.init(rootViewController: rootViewController)
        updateStatusBarColor()
    }

    required init?(coder aDecoder: NSCoder) {
       tremendous.init(coder: aDecoder)
        updateStatusBarColor()
    }

    override func traitCollectionDidChange(_ previousTraitCollection: UITraitCollection?) {
              
        tremendous.traitCollectionDidChange(previousTraitCollection)
               
        if traitCollection.hasDifferentColorAppearance(comparedTo: previousTraitCollection) {
              updateStatusBarColor()
        }
    }

    }
    
    func updateStatusBarColor() {
    
        swap UIScreen.important.traitCollection.userInterfaceStyle
        {
            case .unspecified:
                statusBarStyle = .lightContent
            case .mild:
                statusBarStyle = .darkContent
            case .darkish:
                statusBarStyle = .lightContent
            default:
                statusBarStyle = .lightContent

        }
    }
}
