複数のピッカーを表示させたい！

二つのピッカーを表示させることはできているのですがそれ以上、表示させることが出来ません。
色々模索したのですがダメでした。
性別と年齢のピッカーは表示できているのですがあとの季節と都道府県が表示できていません。
関連付け等はしております。
模索した方法としましては 1個目のピッカーの設定
return agedataList.count
}else{
return seibetudataList.count
}
return agedataList.count
にてreturn seasonListなどを追加しましたがダメでした。
どうか教えていただきたいと思います。よろしくお願いします。

import UIKit

class secondViewController: UIViewController,UIPickerViewDelegate,UIPickerViewDataSource {
    
    @IBOutlet weak var seibetupicker: UIPickerView!
    @IBOutlet weak var agepicker: UIPickerView!
    @IBOutlet weak var seasonpicker: UIPickerView!
    @IBOutlet weak var Prefecturespicker: UIPickerView!

    let seibetudataList = ["指定なし","男性","女性","不明"]
    let agedataList = ["指定なし","10代","20代","30代","40代","50代","60代","70代","80代","90代"]
    let seasonList = ["指定なし","春","夏","秋","冬"]
    let PrefecturesList = ["北海道","青森県","岩手県","宮城県","秋田県","山形県","福島県","茨城県","栃木県","群馬県","埼玉県","千葉県","東京都","神奈川県","新潟県","富山県","石川県","福井県","山梨県","長野県","岐阜県","静岡県","愛知県","三重県","滋賀県","京都府","大阪府","兵庫県","奈良県","和歌山県","鳥取県","島根県","岡山県","広島県","山口県","徳島県","香川県","愛媛県","高知県","福岡県","佐賀県","長崎県","熊本県","大分県","鹿児島県","沖縄県"]

        agepicker.numberOfRows(inComponent: 0)
        // Dispose of any resources that can be recreated.
    }
    func numberOfComponents(in pickerView: UIPickerView) -> Int {
        // 表示する列数
        return 1
    }
    func pickerView(_ pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int {
        // アイテム表示個数を返す
        if pickerView == agepicker {
            // 1個目のピッカーの設定
            return agedataList.count
        }else{
            return seibetudataList.count
        }
        return agedataList.count
    }
    // UIPickerViewDelegate
    
    func pickerView(_ pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String? {
        // 表示する文字列を返す
        if pickerView == agepicker  {
            // 1個目のピッカーの設定
            return agedataList[row]
        }else {
            return seibetudataList[row]
        }
        return agedataList[row]
    }
    
    func pickerView(_ pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) {
        if pickerView == seibetupicker {
            selectedSeibetu = seibetudataList[row]
        }
    }

delegateにpickerView(_:numberOfRowInComponent:)がありますよね。これを

swift
1    func pickerView(_ pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int {
2        
3        switch pickerView {
4        case agepicker:
5            return agedataList.count
6        case seibetupicker:
7            return seibetudataList.count
8        case seasonpicker:
9            return seasonList.count
10        case Prefecturespicker:
11            return PrefecturesList.count
12        default:
13            fatalError()
14        }
15        
16//        if pickerView == agepicker {
17//            return agedataList.count
18//        } else if pickerView == seibetupicker {
19//            return seibetudataList.count
20//        } else if pickerView == seasonpicker {
21//            return seasonList.count
22//        } else {
23//            return PrefecturesList.count
24//        }
25        
26    }

とやってpickerView(_:titleForRow:forComonent:)を

swift
1func pickerView(_ pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String? {
2        if pickerView == agepicker {
3            return agedataList[row]
4        } else if pickerView == seibetuPicker {
5            return seibetudataList[row]
6        } else if pickerView == seasonPicker {
7            return seasonList[row]
8        } else {
9            return prefecturesList[row]
10        }
11    }
