Code of ViewController (code of file from where you want to pass value):

import UIKit

class ViewController: UIViewController {

    @IBOutlet weak var txt1: UITextField!
    override func viewDidLoad() {
        super.viewDidLoad()
       
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
      
    }

    @IBAction func ClickToPass(_ sender: Any) {
        let mmi  = self.storyboard?.instantiateViewController(withIdentifier: "Second") as! SecondViewController
       
        mmi.passedvalue = txt1.text!
        self.navigationController?.pushViewController(mmi, animated: true)
    }
    

}


Code of SecondViewController (code of file where you want to get value):

import UIKit

class SecondViewController: UIViewController {

    @IBOutlet weak var label1: UILabel!
    var passedvalue = String()
    override func viewDidLoad() {
        super.viewDidLoad()

        label1.text = "Passed value= " + passedvalue
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }
}
