RxSwift + RxRealmで複数セクションに対応したDataSourceを作ってみたけどまだ欲しいものになってない感じ #CodePiece

CodePiece.swift

public class Section: Object, RealmSectionModelType {
    public typealias Item = RowItem
    public let item = List<Item>()
    @objc dynamic var title = ""
}

public class RowItem: Object {
    @objc dynamic var title = ""
}

class ViewController: UIViewController {
    @IBOutlet weak var tableView: UITableView!
    let realm = try! Realm()

    override func viewDidLoad() {
        let realmSectionedDataSource = RxRealmSectionedDataSources<Section>(configureCell: { ds, tableView, indexPath, item in
            //...
            cell.title.text = item.title
        })

        realmSectionedDataSource.titleForHeaderInSection = { tv, section in
            return realmSectionedDataSource.sectionsModel?[section].title
        }

        Observable.sectionedChangeset(from: realm.objects(Section.self))
            .bind(to: tableView.rx.items(dataSource: realmSectionedDataSource))
            .disposed(by: disposeBag)
    }
}
