如何修复从调试存储器图xcode中的内存泄漏

Question

我正在尝试通过调试内存图和struct在此处修复内存泄漏。

我的代码在uicollectionView中，cellforitemat indexpath如下

guard let cell = collectionView?.dequeueReusableCell(withReuseIdentifier: cellIdentifier, for: indexPath) as? DiscoveryCell else {
        Log.error("DiscoveryCell not registered")
        return UICollectionViewCell()
      }
    let buttonView = self.delegate?.getBottomView(template: viewModel)
cell.configure(model: viewModel, buttonView: buttonView)
return cell

，自定义单元包含

class DiscoveryCell: UICollectionViewCell, Identifiable {
private(set) var viewModel: DiscoveryProtocol?
@IBOutlet private var buttonContainerView: UIView!

func configure(model: DiscoveryProtocol, buttonView: UIView?) {
    guard let viewModel = model as? DiscoveryProtocol else {
      return
    }
    self.viewModel = viewModel

if let actionButtonView = buttonView {
      actionButtonView.frame = buttonContainerView.bounds
      self.buttonContainerView.addSubview(actionButtonView)
    }
  }

  override func prepareForReuse() {
    super.prepareForReuse()
        self.buttonContainerView.subviews.forEach { subview in
      subview.removeFromSuperview()
    }
  }
}

我的代码有什么问题？我的意思是在哪里找到内存泄漏
