Show other array in next view controller depending on button pressed in previous

I spent hours to make this work but I am trying to show an array in a view controller based on the button that is pressed in the previous view. So I want to use the same view controller but with different data.

In the view controller:

@IBAction func firstDeck(_ sender: UIButton) {
var dataSource : CardsDataModel? {
        
    didSet {
        label.text = cardsDeck.FirstDate()
        } 
    }
}

@IBAction func secondDeck(_ sender: UIButton) {
var dataSource : CardsDataModel? {

            didSet {
           label.text = cardsDeck.PizzaFriends()
         }
    }
}

So there are two cardDecks: PizzaFriends and FirstDates. I tried using IBAction from the buttons to then show the relevant cardsDeck but without success. The cards are empty.

Declare an Array of String type variable in NextViewController

var someData = [String]()

In viewDidLoad() method of NextViewController add this

print("Some Data: \(someData)")

In the PreviousViewController in the IBAction methods present/push the NextViewController with assign someText variable according to which button has been pressed

@IBAction func firstDeck(_ sender: UIButton) {
    let vc = NextViewController()
    vc.someData = cardsDeck.FirstDate()

    // If you want to present NextViewController
    present(vc, animated: true, completion: nil)

    // If you want to push NextViewController to navigation stack
    //navigationController?.pushViewController(vc, animated: true)
}

@IBAction func secondDeck(_ sender: UIButton) {
    let vc = NextViewController()
    vc.someData = cardsDeck.PizzaFriends()

    // If you want to present NextViewController
    present(vc, animated: true, completion: nil)

    // If you want to push NextViewController to navigation stack
    //navigationController?.pushViewController(vc, animated: true)
}

Here is a sample NextViewController

class NextViewController: UIViewController {
    
    var someData = [String]()
    
    var cardView = SwipeCardView(frame: CGRect(x: 10, y: 150, width: 300, height: 600))

    override func viewDidLoad() {
        super.viewDidLoad()
        
        self.view.backgroundColor = .white
        
        self.view.addSubview(cardView)
        
        cardView.label.text = "\(someData)"
    }
}
