ios – scroll view will not scroll

I’ve the next code

    let scrollView = UIScrollView()
    scrollView.translatesAutoresizingMaskIntoConstraints = false
    scrollView.showsVerticalScrollIndicator = false
    scrollView.showsHorizontalScrollIndicator = false
    scrollView.bounces = true
    self.view.addSubview(scrollView)

    NSLayoutConstraint.activate([
        scrollView.leadingAnchor.constraint(equalTo: self.view.leadingAnchor),
        scrollView.trailingAnchor.constraint(equalTo: self.view.trailingAnchor),
        scrollView.topAnchor.constraint(equalTo: progressView.bottomAnchor, constant: 20),
        scrollView.bottomAnchor.constraint(equalTo: self.view.bottomAnchor)
    ])
    
    // Create the UILabels, UIImageView, and UIButton
    let titleLabel = UILabel()
    titleLabel.textual content = "Your Intelligence Sorts"
    titleLabel.font = UIFont(title: "Inter-Daring", measurement: 20)
    titleLabel.textAlignment = .middle
    
    titleLabel.translatesAutoresizingMaskIntoConstraints = false
    scrollView.addSubview(titleLabel)
    
    // Set constraints for the stackView
    NSLayoutConstraint.activate([
        titleLabel.topAnchor.constraint(equalTo: scrollView.safeAreaLayoutGuide.topAnchor, constant: 20),
        titleLabel.leadingAnchor.constraint(equalTo: scrollView.leadingAnchor, constant: 20),
        titleLabel.trailingAnchor.constraint(equalTo: scrollView.trailingAnchor, constant: -20),
        titleLabel.heightAnchor.constraint(equalToConstant: 30)
    ])
    
    // Create the UILabels, UIImageView, and UIButton
    let descriptionLbl = UILabel()
    descriptionLbl.textual content = "Various kinds of intelligence spotlight the varied methods individuals assume, remedy issues, and work together with the world round them."
    descriptionLbl.font = UIFont(title: "Inter-Common", measurement: 14)
    descriptionLbl.textAlignment = .left
    descriptionLbl.numberOfLines = 0
    
    descriptionLbl.translatesAutoresizingMaskIntoConstraints = false
    scrollView.addSubview(descriptionLbl)
    
    // Set constraints for the stackView
    NSLayoutConstraint.activate([
        descriptionLbl.topAnchor.constraint(equalTo: titleLabel.bottomAnchor, constant: 20),
        descriptionLbl.leadingAnchor.constraint(equalTo: scrollView.leadingAnchor, constant: 20),
        descriptionLbl.widthAnchor.constraint(equalToConstant: 350),
        descriptionLbl.heightAnchor.constraint(equalToConstant: 60)
    ])
    
    var previousProgressView : UIProgressView? = nil
    let previousTitleHeight: CGFloat = 30
    let progressViewHeight: CGFloat = 20
    let labelHeight: CGFloat = 20
    let verticalSpacing: CGFloat = 20

    var n = 0;
    for (key, worth) in totalTypes {
        let typeLabel = UILabel()
        typeLabel.textual content = key
        typeLabel.font = UIFont(title: "Inter-Daring", measurement: 16)
        typeLabel.textAlignment = .left
        
        typeLabel.translatesAutoresizingMaskIntoConstraints = false
        
        let iprogressView = UIProgressView(progressViewStyle: .bar)
        iprogressView.trackTintColor = UIColor(pink: 0.07, inexperienced: 0.45, blue: 0.87, alpha: 0.1)
        iprogressView.tintColor = UIColor(pink: 0.07, inexperienced: 0.45, blue: 0.87, alpha: 1.00)
        iprogressView.layer.cornerRadius = 4
        iprogressView.clipsToBounds = true
        iprogressView.setProgress(Float(userTypes[key] ?? 0) / Float(worth), animated: true)
        iprogressView.translatesAutoresizingMaskIntoConstraints = false
    
        let rework : CGAffineTransform = CGAffineTransform(scaleX: 1.0, y: 3.0)
        iprogressView.rework = rework
        
        let progressLabel = UILabel()
        let progressValue = spherical(((Float(userTypes[key] ?? 0) / Float(worth)) * 100) * 100) / 100
        progressLabel.textual content = "(progressValue) %"
        progressLabel.translatesAutoresizingMaskIntoConstraints = false
        progressLabel.font = UIFont(title: "Inter-Common", measurement: 16)
        
        scrollView.addSubview(typeLabel)
        scrollView.addSubview(iprogressView)
        scrollView.addSubview(progressLabel)
        
        NSLayoutConstraint.activate([
            typeLabel.topAnchor.constraint(equalTo: previousProgressView?.bottomAnchor ?? descriptionLbl.bottomAnchor, constant: previousProgressView == nil ? verticalSpacing : verticalSpacing),
            typeLabel.leadingAnchor.constraint(equalTo: scrollView.leadingAnchor, constant: 20),
            typeLabel.trailingAnchor.constraint(equalTo: scrollView.trailingAnchor, constant: -20),
            typeLabel.heightAnchor.constraint(equalToConstant: 20),
            
            iprogressView.topAnchor.constraint(equalTo: typeLabel.bottomAnchor, constant: 20),
            iprogressView.leadingAnchor.constraint(equalTo: scrollView.leadingAnchor, constant: 20),
            iprogressView.widthAnchor.constraint(equalToConstant: 200),
            iprogressView.heightAnchor.constraint(equalToConstant: 3),
            
            // Position the label next to the progressView
            progressLabel.leadingAnchor.constraint(equalTo: iprogressView.trailingAnchor, constant: 10),
            progressLabel.centerYAnchor.constraint(equalTo: iprogressView.centerYAnchor)
        ])
        
        // Replace the previousProgressView reference
        previousProgressView = iprogressView
        n += 1
    }

    // Set the content material measurement of the scrollView
    let totalContentHeight = (CGFloat(totalTypes.rely) * (labelHeight + progressViewHeight + verticalSpacing + CGFloat(100))) + verticalSpacing + CGFloat(2000)
    scrollView.contentSize = CGSize(width: self.view.body.width, top: totalContentHeight)

The issue is the scrollview will not scroll regardless that I set the content material measurement. Can somebody please assist?
