Try to add this in your controller

    func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
        return UITableView.automaticDimension
    }
    
    func tableView(_ tableView: UITableView, estimatedHeightForRowAt indexPath: IndexPath) -> CGFloat {
        return UITableView.automaticDimension
    }

Your question is vague.

You suppose to provide an example of what you're trying to achieve.

Suppose you have static height for collection view cell: Easy, auto layout will be your friend. Using:

func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
        return UITableView.automaticDimension
    }
    
    func tableView(_ tableView: UITableView, estimatedHeightForRowAt indexPath: IndexPath) -> CGFloat {
        return UITableView.automaticDimension
    }

However, if you would like to dynamically layout table view cell height:

1. Set height constraint for minimum height of collection view cell
2. Calculate the content size:

// You may need to call it when viewDidLayoutSubviews() is called
let height = collectionView.collectionViewLayout.collectionViewContentSize.height
collectionViewHeightConstraint.constant = height
contentView.layoutIfNeeded()
