RxInstantiate

Useful protocols and default implementation using RxSwift, RxDataSources and Instantiate.

LazyVariable

No Error ReplaySubject(1) wrapper. Don't need to inital value when init LazyVariable, but should set value before get value.

RxViewProtocol

Actual view/viewController may have own ViewModel. In this case, ViewModel should be Injectable that has same Dependency of view/viewController, maybe useful that using LazyVariable.
RxViewProtocol have default implementation of func inject that injecting value to ViewModel. It mean view/viewController that implemented Instantiatable and RxViewProtocol is require only binding with ViewModel.

RxDataSources extensions

The cell type that implemented Reusable, can make default implementation of reuse cell and data binding.
RxInstantiate take function that generate RxDataSource instance.

1TableView(CollectionView) - 1Cell case

observable.bind(to: tableView.rx.items(.reload, for: Cell.self)) is same of make RxTableViewSectionedReloadDataSource instance and setup configureCell.
The observable value type should be [SectionModelType] and the SectionModelType.Item should be equal to Cell.Dependency.

1TableView(CollectionView) - nCell case (2≤n≤5)

observable.bind(to: tableView.rx.items(.reload, for: Cell1.self, Cell2.self, ...)) is same of make RxTableViewSectionedReloadDataSource instance and setup configureCell.
The observable value type should be [SectionModelType] and the SectionModelType.Item should implement EnumNConvertible and there case type should be equal to Cell1.Dependency , Cell2.Dependency and so on.

Needs 6 or more Cell...

It may be a bit complicated for your user, but can use environment variable ENUM_CONVERTIBLE_MAX_SERIAL_NUMBER or ENUM_CONVERTIBLE_SPECIFIC_NUMBERS. Please check enum-convertible
