Set Status bar in AppDelegate? - swift

Question

Previously, I had this code and it worked perfectly before Swift was updated. Now it says:
Setter for 'statusBarStyle' was deprecated in iOS 9.0: Use -[UIViewController preferredStatusBarStyle]
Now, I read that you have to override the statusBarStyle but I don't want to do this manually in each UIViewController but instead, control it via a struct and an extension of the UIApplication. Not sure how to do that though.
The code:
extension UIApplication {
var statusBarView: UIView? {
return value(forKey: "statusBar") as? UIView
}
}
struct StatusBar {
static func setStatusBar() {
let appDelegate = UIApplication.shared.delegate as? AppDelegate
if let currentVC = appDelegate?.window?.rootViewController?.getCurrentlyDisplayedVC() {
if currentVC is LoginVC || currentVC is SignUpVC || currentVC is SignUpVC {
UIApplication.shared.statusBarView?.backgroundColor = .clear
}
else {
UIApplication.shared.statusBarView?.backgroundColor = Colors.mainBlueColor
}
}
UIApplication.shared.statusBarStyle = .lightContent
}
}
extension UIViewController {
func getCurrentlyDisplayedVC() -> UIViewController {
if let presentedVC = presentedViewController {
return presentedVC.getCurrentlyDisplayedVC()
}
else if let split = self as? UISplitViewController, let last = split.viewControllers.last {
return last.getCurrentlyDisplayedVC()
}
else if let nav = self as? UINavigationController, let top = nav.topViewController {
return top.getCurrentlyDisplayedVC()
}
else if let tab = self as? UITabBarController {
if let selected = tab.selectedViewController {
return selected.getCurrentlyDisplayedVC()
}
}
return self
}
}
