Swift UICollectionViewCompostionalLayout Collectionview单元格宽度在重新加载数据后未正确调整大小

我正在使用UICollectionViewCompostionalLayout在我的集合视图的某些部分中创建动态宽度、固定高度、标记单元格类型的布局.当我向数据库中的数组添加新字符串、将数组重新加载到数据源并执行集合视图重新加载数据时，单元格以一种不可预测的方式调整大小.有时它们调整大小以适合字符串的宽度，有时它们似乎使用单元格的估计宽度并截断字符串.对如何解决这个问题有什么建议吗？我已经在下面发布了一张gif.

以下是我的makelayout函数(简化并删除了不必要的代码行):

override func makeLayout() -> UICollectionViewLayout {
        let layout = UICollectionViewCompositionalLayout(sectionProvider: { (sectionIndex, environment) -> NSCollectionLayoutSection? in


        let itemSize = NSCollectionLayoutSize(widthDimension: .estimated(40), heightDimension: .absolute(40))
        let item = NSCollectionLayoutItem(layoutSize: itemSize)
        let inset: CGFloat = 10
        item.contentInsets = NSDirectionalEdgeInsets(top: inset, leading: inset, bottom: inset, trailing: inset)
            
        let groupSize = NSCollectionLayoutSize(widthDimension: .fractionalWidth(1.0), heightDimension: .absolute(40))
        let group = NSCollectionLayoutGroup.horizontal(layoutSize: groupSize, subitems: [item])
        group.interItemSpacing = NSCollectionLayoutSpacing.fixed(CGFloat(10))
        let section = NSCollectionLayoutSection(group: group)
        section.interGroupSpacing = CGFloat(10.0)
        section.contentInsets = NSDirectionalEdgeInsets(top: 0, leading: 20, bottom: 0, trailing: 20)
        section.supplementariesFollowContentInsets = false

        return section
          
    })
        
        
    let config = UICollectionViewCompositionalLayoutConfiguration()
    config.scrollDirection = .vertical
    config.interSectionSpacing = 10
    layout.configuration = config
      
    return layout
}

这是我自定义集合视图单元格

class CollectionViewCell: UICollectionViewCell {
    
    lazy var textLabel: UILabel = {
        let label = UILabel()
        label.font = UIFont(name: "Stolzl-Regular", size: 12)
        label.textAlignment = NSTextAlignment.left
        label.backgroundColor = .clear //.red
        label.textColor = .white
        label.text = ""
        label.numberOfLines = 0
        label.translatesAutoresizingMaskIntoConstraints = false
        label.lineBreakMode = NSLineBreakMode.byWordWrapping
        return label
    }()
    
    override init(frame: CGRect) {
        super.init(frame: frame)

        setupLabel()

    }
    
    func setupLabel(){
        addSubview(textLabel)
        addConstraintsWithFormat("H:|-10-[v0]-10-|", views: textLabel)
        addConstraintsWithFormat("V:|-10-[v0]-10-|", views: textLabel)
    }

    override func prepareForReuse() {
        super.prepareForReuse()

    }
    
    required init?(coder aDecoder: NSCoder) {
        fatalError("init(coder:) has not been implemented")
    }
}
