You cannot change those properties for the status bar. You can only set, .default, .lightContent. But if you want you can probably place a view underneath of it, which is not translucent and has a background color. Something like this:

let statusBarFrame = UIApplication.shared.statusBarFrame
let statusBarView = UIView(frame: statusBarFrame)
self.view.addSubview(statusBarView)
statusBarView.backgroundColor = .green

That can go in you viewDidLoad() method of the ViewController

Swift 5.1 iOS 13.0 Just in case for the current deprecations...

 if #available(iOS 13.0, *) {

            let window = UIApplication.shared.windows.filter {$0.isKeyWindow}.first
            let statusBarFrame = window?.windowScene?.statusBarManager?.statusBarFrame

            let statusBarView = UIView(frame: statusBarFrame!)
            self.view.addSubview(statusBarView)
            statusBarView.backgroundColor = .green
        } else {
            //Below iOS13
            let statusBarFrame = UIApplication.shared.statusBarFrame
            let statusBarView = UIView(frame: statusBarFrame)
            self.view.addSubview(statusBarView)
            statusBarView.backgroundColor = .green
        }

This fixed it for me when trying to slide a view from above into the screen, without seeing it on status bar while it animates:

view.clipsToBounds = true
