RxDataSourcesViewModels

RxDataSourcesViewModels is a lightweight library that allows you to easily use your ViewModels with RxDataSources.

You don’t need to do all the DataSource boilerplate to configure your cells for each TableView of your project anymore.

1- Implement CellViewModelType protocol in your ViewModel:

import RxDataSourcesViewModels

class MyCellViewModel: CellViewModelType {

    // Return the cell identifier here. 
    var cellIdentifier: String {
        return "MyCellViewModelIdentifier"
    }
}

2- Implement CellViewModelConfigurable protocol in your Cells:

import RxDataSourcesViewModels

class MyCell: UITableViewCell, CellViewModelConfigurable {

    func configure(with viewModel: CellViewModelType) {
        
        // Cast to your specific ViewModel type.
        guard let viewModel = viewModel as? MyCellViewModel else { return }
        
        // Configure your cell with its ViewModel here...
    }
}

3- Bind your Driver of Sections to your TableView or CollectionView:

import UIKit
import RxSwift
import RxDataSourcesViewModels

class MyViewController: UIViewController {

    let viewModel = MyViewModel()
    let dataSource = ViewModelsDataSource<String>()
    let disposeBag = DisposeBag()
    
    override func viewDidLoad() {
        super.viewDidLoad()
        bind()
    }

    func bind() {
        viewModel.sections
            .drive(tableView.rx.items(dataSource: dataSource))
            .disposed(by: disposeBag)
    }
}
