Printing pdf file in webview

I want to add a print Button into my app to print local pdf files.

So I added a UIToolBar + UIBarButtonItem and linked it with my following code:

@IBAction func printButton(_ sender: Any) {

    let printController = UIPrintInteractionController.shared

    let printInfo = UIPrintInfo(dictionary:nil)

    printInfo.outputType = UIPrintInfo.OutputType.general

    printInfo.jobName = (wkWebView.url?.absoluteString)!

    printInfo.duplex = UIPrintInfo.Duplex.none

    printInfo.orientation = UIPrintInfo.Orientation.portrait

    printController.printPageRenderer = nil

    printController.printingItems = nil

    printController.printingItem = wkWebView.url!

    printController.printInfo = printInfo

   // printController.showsPageRange = true

    printController.showsNumberOfCopies = true


    printController.presentFromBarButtonItem(printButton, animated: true, completionHandler: nil)

}

On the last line I get this error message:

Cannot convert value of type '(Any) -> ()' to expected argument type 'UIBarButtonItem'

I tried different ways but I'm stuck. It would be awesome if someone can help me. I think it's easy to solve but not at the moment for me.

You are required to pass the argument as bar button. But you are passing sender, which is "Any" at the moment.. either use a guard to downcast it as bar button like

 guard let barButton = sender as? UIBarButtonItem else {
            print("not bar button")
            return
        }
 printController.presentFromBarButtonItem(barButton, animated: true, completionHandler: nil)

Or change the sender to 

IBAction func printButton(_ sender: UIBarButtonItem)

 printController.presentFromBarButtonItem(sender, animated: true, completionHandler: nil)

Remove action than try to addAction with sender

IBAction func printButton(_ sender: Any) //instead  of
IBAction func printButton(_ sender: UIBarButtonItem)
