Call UIButton from String Programmatically – Ios swift

This is my code for my CollectionViews. I have two CollectionViews so far, and as you can see in the Strings in the code, they each have 6 buttons. I need to call the buttons from the Strings so that when they are pressed, a new window opens. The new window will contain things like flashcards, pertaining to the subject of the button that was pressed.

For reference, is what the simulator looks like.

code:

import UIKit

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view.
    }


}

class FirstCollectionViewCell: UICollectionViewCell {
    
    @IBOutlet weak var buttonOne: UIButton!
    
    override func awakeFromNib() {
        super.awakeFromNib()
        commonInit()
    }
    func commonInit() {
        guard buttonOne != nil else { return }
        buttonOne.titleLabel!.font = UIFont(name: "Marker Felt", size: 20)
        buttonOne.layer.cornerRadius = 10
        buttonOne.clipsToBounds = true
        buttonOne.layer.borderWidth = 1.0
        buttonOne.layer.borderColor = UIColor.white.cgColor
        }
    }

class SecondCollectionViewCell: UICollectionViewCell {

    @IBOutlet weak var buttonTwo: UIButton!
    override func awakeFromNib() {
        super.awakeFromNib()
        commonInit()
    }
    func commonInit() {
        guard buttonTwo != nil else { return }
        buttonTwo.titleLabel!.font = UIFont(name: "Marker Felt", size: 20)
        buttonTwo.layer.cornerRadius = 10
        buttonTwo.clipsToBounds = true
        buttonTwo.layer.borderWidth = 1.0
        buttonTwo.layer.borderColor = UIColor.white.cgColor
    }
}

class TwoCollectionsViewController: UIViewController, UICollectionViewDataSource, UICollectionViewDelegate {
    @IBOutlet weak var firstCV: UICollectionView!
    @IBOutlet weak var secondCV: UICollectionView!
    
    @IBAction func Buttons(_ sender: Any) {
        if let btn = sender as? UIButton {
            print(btn.restorationIdentifier!)
                guard let button = sender as? UIButton else { return }
                guard let id = Int(button.restorationIdentifier!) else {return}
                if id < firstData.count {
                 performSegue(withIdentifier: "Good Work", sender: btn)
                }
                else {
                 performSegue(withIdentifier: "Nice Try", sender: btn)
                }
                print(button.restorationIdentifier!)
               
        }
        
    }
    
    let firstData: [String] = [
        "Good Work", "Nice Try", "Btn 3", "Btn 4", "Btn 5", "Btn 6"
    ]

    let secondData: [String] = [
        "Second 1", "Second 2", "Second 3", "Second 4", "Second 5", "Second 6"
    ]

    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        firstCV.dataSource = self
        firstCV.delegate = self
        
        secondCV.dataSource = self
        secondCV.delegate = self
    }
    
    func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
        // if it's the First Collection View
        if collectionView == firstCV {
            return firstData.count
        }
        
        // it's not the First Collection View, so it's the Second one
        return secondData.count
    }
    
    func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
        
        // if it's the First Collection View
        if collectionView == firstCV {
            let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "firstCell", for: indexPath) as! FirstCollectionViewCell
            cell.buttonOne.setTitle(firstData[indexPath.item], for: []) //allows for button title change in code above
           cell.buttonOne.restorationIdentifier = "(indexPath.row + firstData.count)"
            return cell
            
            
        }
        
        // it's not the First Collection View, so it's the Second one
        let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "secondCell", for: indexPath) as! SecondCollectionViewCell
        cell.buttonTwo.setTitle(secondData[indexPath.item], for: [])
        cell.buttonTwo.restorationIdentifier = "(indexPath.row)"
        return cell
