Cannot convert value of type 'Timer' to expected argument type '(() -> Void)?' Swift 5

Question

I am facing an issue while adding Timer inside the completion block of the present alert controller.

Error: Cannot convert value of type 'Timer' to expected argument type '(() -> Void)?'

func showAutoHideAlert() {
    let alertController = UIAlertController(title: "title", message: "message", preferredStyle: .alert)
    present(alertController, animated: true, completion: Timer.scheduledTimer(withTimeInterval: 3.0, repeats: false) { _ in
        self.dismiss(animated: true, completion: nil)
    })
}

Please help how to resolve this issue. Thanks
