Not able to save selected value from a UIPickerView to an array

So far I have tried to use

func pickerView1(_ helpTypePicker: UIPickerView, didSelectRow row: Int, inComponent component: Int {   infoListInit.requestInfoList[4] = (helpTypePickerValues[row]) }

But the value is just not saving to the array. I tried printing the value after saving it, but to no avail. I do have helpTypePicker as a self delegate in my viewDidLoad func, so I don't know where to go from here. Other text values from UITextFields save fine, but none of my UIPickerViews are working in this regard

Here is the full class:

import Foundationimport UIKitclass requestHelpTypePickerScreen: UIViewController, UIPickerViewDataSource, UIPickerViewDelegate {func numberOfComponents(in pickerView: UIPickerView) -> Int {    return 1}func pickerView(_ pickerView: UIPickerView, numberOfRowsInComponent  component: Int) -> Int {    if pickerView.tag == 1 {        return helpTypePickerValues.count    } else {        return languagePickerValues.count    }}func pickerView(_ pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String? {    if pickerView.tag == 1 {        return "\(helpTypePickerValues[row])"    } else {        return "\(languagePickerValues[row])"    }}// Mark: outlets@IBOutlet weak var helpTypePicker: UIPickerView!@IBOutlet weak var languagePicker: UIPickerView!@IBOutlet weak var helpTypePickerLabel: UILabel!let helpTypePickerValues = ["Academic/Professional", "Donate", "Food/Groceries", "Medication", "Emotional Support", "Misc."]let languagePickerValues = ["Arabic", "Chinese", "Spanish", "English", "French", "Hindi/Urdu", "Korean", "Russian"]override func viewDidLoad() {    super.viewDidLoad()    helpTypePicker.delegate = self    languagePicker.delegate = self    self.helpTypePicker.selectRow(2, inComponent: 0, animated: true)    self.languagePicker.selectRow(3, inComponent: 0, animated: true)}// Mark: actions@IBAction func buttonPressed(_ sender: Any) {    func pickerView(_ helpTypePicker: UIPickerView,    didSelectRow row: Int,    inComponent component: Int) {        infoListInit.requestInfoList[5] = (helpTypePickerValues[row])    }    // this is called pickerView1 because it would conflict with the above     // function if called pickerView    func pickerView1(_ languagePicker: UIPickerView,    didSelectRow row1: Int,    inComponent component: Int) {        infoListInit.requestInfoList[6] = (languagePickerValues[row1])    }    performSegue(withIdentifier: "pickersDone", sender: nil)}
