import UIKit

class ViewController: UIViewController, UIPickerViewDataSource, UIPickerViewDelegate {
    @IBOutlet weak var pickerView: UIPickerView!
    @IBOutlet weak var selectedOptionLabel: UILabel!

    let options = ["Option 1", "Option 2", "Option 3"]

    override func viewDidLoad() {
        super.viewDidLoad()
        
        pickerView.dataSource = self
        pickerView.delegate = self
    }

    // MARK: - UIPickerViewDataSource
    
    func numberOfComponents(in pickerView: UIPickerView) -> Int {
        return 1
    }
    
    func pickerView(_ pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int {
        return options.count
    }
    
    // MARK: - UIPickerViewDelegate
    
    func pickerView(_ pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String? {
        return options[row]
    }
    
    func pickerView(_ pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) {
        let selectedOption = options[row]
        selectedOptionLabel.text = selectedOption
    }
