UIViewの長さに応じてUIScrollViewの長さを変える方法は？

UILabelを複数個UIViewに乗せ、そのUIViewの長さに応じてUIScrollViewの長さを変えたいと思っています。
SizeToFitを使った方法はUIViewにもUIScrollViewにもあるようですが、
コードに書いても効果がありませんでした。
現時点でのコードでは縦にスクロールすることができません。

コードはこちらです。

swift
1override func viewDidLoad() {
2        super.viewDidLoad()
3        
4        self.view.backgroundColor = UIColor.white
5        
6        self.navigationController?.setNavigationBarHidden(true, animated: false)
7        
8        var tokyoCount = 0
9        var tokyoArray = [0]

11        // CSV読み込み
12        if let csvPath = Bundle.main.path(forResource: "mise", ofType: "csv") {
13            do {
14                var csvString =  try NSString(contentsOfFile: csvPath, encoding: String.Encoding.utf8.rawValue) as String
15                csvString = csvString.replacingOccurrences(of: "\r\n", with: "")
16                let array2:Array = csvString.components(separatedBy: ",")
17

19                array2.enumerated().forEach { (index, value) in
