      let alert = UIAlertController( title: "Post Something", message: "what would you like to post?",preferredStyle: .alert)
      alert.addTextField{(textField) in textField.placeholder = "Enter Message here"}
  
      let cancel = UIAlertAction(title: "Cancel" , style: .cancel, handler:nil)
      let post = UIAlertAction(title: "Post", style: .default){
          _ in guard let text = alert.textFields?.first?.text else{return}
          print(text)
      }
      alert.addAction(cancel)
      alert.addAction(post)
      present(alert, animated: true, completion: nil)
  
  
  
  }
