How to properly add an UICollectionView inside UITableViewCell using IOS 12

For some reasons I cannot properly display some items from a collection inside an tableview cell when using Xcode 10 beta. I tried all I know for the last 4 days.

I made a small project sample to see what my issue is.
Full code is here if someone wants to run it locally: https://github.com/adrianstanciu24/CollectionViewInsideUITableViewCell

I first add an table view with 2 different resizable cells, first cell has the collection view and a label:

class ViewController: UIViewController, UITableViewDataSource, UITableViewDelegate {

    @IBOutlet weak var tableView: UITableView!

    override func viewDidLoad() {
        super.viewDidLoad()

        tableView.delegate = self
        tableView.dataSource = self
        tableView.estimatedRowHeight = 44
        tableView.rowHeight = UITableView.automaticDimension
    }

    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return 2
    }

    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        if indexPath.row == 0 {
            let cell = tableView.dequeueReusableCell(withIdentifier: "collCell") as! CollectionTableViewCell
            cell.collectionView.collectionViewLayout.invalidateLayout()

            return cell
        } else {
            let cell = tableView.dequeueReusableCell(withIdentifier: "normalCell")!

            return cell
        }
    }
}

Here is the cell with collection view defined. This also has a height constraint which I updated in layoutSubviews:

class CollectionTableViewCell: UITableViewCell, UICollectionViewDataSource, UICollectionViewDelegateFlowLayout, UICollectionViewDelegate {

    @IBOutlet weak var collectionView: UICollectionView!
    @IBOutlet weak var collectionViewHeightConstraint: NSLayoutConstraint!


    override func awakeFromNib() {
        super.awakeFromNib()

        collectionView.delegate = self
        collectionView.dataSource = self

        if let layout = collectionView.collectionViewLayout as? UICollectionViewFlowLayout {
            layout.estimatedItemSize = UICollectionViewFlowLayout.automaticSize
        }
    }

    override func layoutSubviews() {
        super.layoutSubviews()
        collectionViewHeightConstraint.constant = collectionView.collectionViewLayout.collectionViewContentSize.height
    }

    func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
        return 10
    }

    func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
        let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "taskCell", for: indexPath as IndexPath) as! TaskCollectionViewCell

        cell.name.text = "Task_" + String(indexPath.row)

        return cell
    }
}

Below is a screenshot with the collection view constraint and how the storyboard looks:

And this is how it looks when running:

The cells are squashed and label on top disappears. What I want is the collection view should grow to show all elements and also making table view cell to resize, but that is not happening at the moment and I can't figure out where the issue is.
