Change Status Bar Background Color in Swift 3

In XCode 7.3.x ill changed the background Color for my StatusBar with:

func setStatusBarBackgroundColor(color: UIColor) {
guard  let statusBar = UIApplication.sharedApplication().valueForKey("statusBarWindow")?.valueForKey("statusBar") as? UIView else {
    return
}
statusBar.backgroundColor = color
}

But it seems that this is not working anymore with Swift 3.0.

Ill tried with:

func setStatusBarBackgroundColor(color: UIColor) {
guard  let statusBar = (UIApplication.shared.value(forKey: "statusBarWindow") as AnyObject).value(forKey: "statusBar") as? UIView else {
    return
}
statusBar.backgroundColor = color
}

But it gives me:

this class is not key value coding-compliant for the key statusBar.

Any Ideas how to change it with XCode8/Swift 3.0?

extension UIApplication {
    var statusBarView: UIView? {
        if responds(to: Selector(("statusBar"))) {
            return value(forKey: "statusBar") as? UIView
        }
        return nil
    }
}

UIApplication.shared.statusBarView?.backgroundColor = .red

Update for iOS 13

App called -statusBar or -statusBarWindow on UIApplication: this code must be changed as there's no longer a status bar or status bar window. Use the statusBarManager object on the window scene instead.
