One way to do it is to create protocols for both your cell view models and your cells, and have specific implementations for each type if cell.

A gist of it could look like this

class BooksPresenter {
    var books: [BookCellViewModel]
}

protocol BookCellViewModel {
    var viewType: BookCellViewType { get }
}

enum BookCellViewType {
    case Type1
    case Type2
}

extension BookCellViewType {
    func reusableIdentifier() -> String {
        switch self {
        case .Type1:
            return "Type1ReusableIdentifier"
        case .Type2:
            return "Type2ReusableIdentifier"
        default:
            return ""
        }
    }
}

protocol BookTableViewCell {
    func configureWith(_ viewModel: BookCellViewModel)
}

With you cellForRow implementation looking like

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let viewModel = presenter.books[indexPath.row]
    
    let cell = tableView.dequeueReusableCell(withIdentifier: viewModel.viewType.reusableIdentifier()) as! BookTableViewCell
    
    cell.configureWith(viewModel)
    
    return cell as! UITableViewCell
}

As you can see there is a bit of casting involved, my Swift skills got a bit rusty in the past couple of years so probably there is a more idiomatic way to do it.
