如何在Swift中返回PickerView中的两个独立数组

import UIKit

class ViewController: UIViewController, UIPickerViewDataSource, UIPickerViewDelegate {
    
    let array1 = ["Option 1", "Option 2", "Option 3"]
    let array2 = ["Choice A", "Choice B", "Choice C"]
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        let pickerView = UIPickerView()
        pickerView.dataSource = self
        pickerView.delegate = self
        
        // 将pickerView添加到视图中
        // ...
    }
    
    // MARK: - UIPickerViewDataSource
    
    func numberOfComponents(in pickerView: UIPickerView) -> Int {
        return 2
    }
    
    func pickerView(_ pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int {
        if component == 0 {
            return array1.count
        } else {
            return array2.count
        }
    }
    
    // MARK: - UIPickerViewDelegate
    
    func pickerView(_ pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String? {
        if component == 0 {
            return array1[row]
        } else {
            return array2[row]
        }
    }
    
    func pickerView(_ pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) {
        if component == 0 {
            let selectedValue = array1[row]
            // 处理选中的值
        } else {
            let selectedValue = array2[row]
            // 处理选中的值
        }
    }
}
