swift - Setting statusbarStyle (deprecated in iOS 9.0)

Question

Just downloaded the new xCode 10.0 and saw that the old statusBarStyle has been deprecated since iOS 9.0.

Warning: Setter for 'statusBarStyle' was deprecated in iOS 9.0: Use -[UIViewController preferredStatusBarStyle]

Deprecated code: UIApplication.shared.statusBarStyle = .default

I tried using self.preferredStatusBarStyle, but found out the property is only a getter. So anyone knows how to set the statusBarStyle?

Edit

I want to change the statusBarStyle inside a function, where a user can switch between different themes. For example:

func changeStatusBar(toDarkMode: Bool) {
    if toDarkMode {
        // Set to light statusBarStyle
    } else { 
        // Set to default
    }
}

Answer 1

Add View controller-based status bar appearance NO in Info.plist

And select Light in Status Bar Style in Deployment Info
