Segue and Button programmatically swift - swift

Question

I am using iCarousel and I have to create my own button. I want to pass data from the button made programmatically to another view, but I don't have a segue identifier because I created the button programmatically. I don't know if it is possible to create the identifier of the segue programmatically.
button.addTarget(self, action: #selector(buttonAction3), for: .touchUpInside)
button.setTitle("\(titulos[index])", for: .normal)
tempView.addSubview(button)
let myImage = UIImage(named: "modo4.png") as UIImage?
button.setImage(myImage, for: .normal)
let viewController:UIViewController = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "modo") as! Modo1ViewController
self.present(viewController, animated: false, completion: nil)
if segue.identifier == "" {
if let destination = segue.destination as? Modo1ViewController {
destination.nomb = nombres
}
}

Answer 1

Create seuge
Assign identifier
and your button target
#IBAction func button_clicked(_ sender: UIButton) {
self.performSegue(withIdentifier: "segueToNext", sender: self)
}
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
if segue.identifier == "segueToNext" {
if let destination = segue.destination as? Modo1ViewController {
destination.nomb = nombres // you can pass value to destination view controller
// destination.nomb = arrayNombers[(sender as! UIButton).tag] // Using button Tag
}
}
}

Answer 2

in your case, if you use self.present and you want to send data between views. Try this:
let viewController:UIViewController = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "modo") as! Modo1ViewController
viewController.nomb = nombres
self.present(viewController, animated: false, completion: nil)
I don't know how to set segue's identifier but I think code above can help
If you want do to easier work, you can create segue in IB (Interface Builder) and set it's identifier, then use
performSegue:withIdentifier:sender
