Answer 1

1.So get rid of this code, because if you are calling performSegue you don’t need that one.

let storyBoard : UIStoryboard = UIStoryboard(name: "Main", bundle:nil)
let nextViewController = storyBoard.instantiateViewController(withIdentifier: "OP") as! OpcionesController
self.present(nextViewController, animated:true, completion:nil)

2.Then in the prepareForSegue

override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
  if segue.identifier == “YourSegueIdentifier" {
    let destination: OpcionesController = segue.destination as! OpcionesController
    destination.name = txtCorreo.text
  }
}

3.Replace this code:

if let nametoDisplay = name {
    displayLbl.text = name
}

with:

displayLbl.text = name
