Sharing text in LinkedIin showing unsuccessful message

Question

Using native sharing text feature by UIActivityViewController. Its successfully posting on share in a post, able to see in my LinkedIn page but showing error message in UI.

    let text = "This is the text....."
    let textShare = [ text ]
    let activityViewController = UIActivityViewController(activityItems: textShare , applicationActivities: nil)
    activityViewController.popoverPresentationController?.sourceView = self.view
    self.present(activityViewController, animated: true, completion: nil)
