如何根据从第一个pickerView中选择的内容来更改第二个选择器视图的数组

import UIKit

class ViewController: UIViewController, UIPickerViewDelegate, UIPickerViewDataSource {
    
    @IBOutlet weak var firstPickerView: UIPickerView!
    @IBOutlet weak var secondPickerView: UIPickerView!
    
    let firstPickerData = ["Category A", "Category B", "Category C"]
    var secondPickerData: [[String]] = [["Option 1", "Option 2", "Option 3"], ["Option 4", "Option 5"], ["Option 6", "Option 7", "Option 8"]]
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        firstPickerView.delegate = self
        firstPickerView.dataSource = self
        secondPickerView.delegate = self
        secondPickerView.dataSource = self
    }
    
    // MARK: - UIPickerViewDataSource
    
    func numberOfComponents(in pickerView: UIPickerView) -> Int {
        return 1
    }
    
    func pickerView(_ pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int {
        if pickerView == firstPickerView {
            return firstPickerData.count
        } else {
            let selectedRow = firstPickerView.selectedRow(inComponent: 0)
            return secondPickerData[selectedRow].count
        }
    }
    
    // MARK: - UIPickerViewDelegate
    
    func pickerView(_ pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String? {
        if pickerView == firstPickerView {
            return firstPickerData[row]
        } else {
            let selectedRow = firstPickerView.selectedRow(inComponent: 0)
            return secondPickerData[selectedRow][row]
        }
    }
    
    func pickerView(_ pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) {
        if pickerView == firstPickerView {
            secondPickerView.reloadComponent(0)
        }
    }
}
