How can I pass data between viewcontrollers? (Swift)

Question

I'm trying to pass data from a ViewController (let's call it ViewControllerA) to a ViewControllerB. I created the ViewControllers programmatically so I am not using the storyboard at all. I would like to display in a UILabel in the ViewControllerB what the user types in a UITextField in ViewControllerA. Is there any way I can do this programmatically? I'm just a beginner so give me the simplest solution you know because it is the easiest one to grasp for me. Thank you!

Think is a sample of the code

ViewControllerA:

import UIKit

class ViewControllerA: UIViewController {

   let player1: UITextField = {
    let p1 = UITextField()
    p1.placeholder = "Player"

    return p1
}()

let goButton: UIButton = {
    let go = UIButton(type: .system)
    go.setTitle("Go!", for: .normal)

    go.addTarget(self, action: #selector(Go), for: .touchUpInside)

    return go
}()



override func viewDidLoad() {
    super.viewDidLoad()
    view.addSubview(player1)
    view.addSubview(goButton)


}

func Go() {
    let viewB = ViewControllerB()
    present(viewB, animated: true, completion: nil)
}

}

ViewControllerB :

import UIKit

class ViewControllerB: UIViewController {

let topLabel: UILabel = {
    let tl = UILabel()
    tl.textColor = UIColor.white

    return tl
}()




override func viewDidLoad() {
    super.viewDidLoad()

    view.addSubview(topLabel)

}

}

(When the user presses the goButton, I'd like the topLabel.text in ViewControllerB to be equal to the player1.text of ViewControllerA)
