Nested Collection

UITableViewCell can contain nested UICollectionView and RxDataSourcesExt let you process it in minimalistic way. To achieve it you need to create view model that implements NestedCollectionTableCellViewModel protocol

structEmbedCollectionCellViewModel:NestedCollectionTableCellViewModel{typealiasTableCellType=EmbedCollectionCellletid:StringletnestedSections:[CollectionSectionModel]letrowHeight:CGFloat=72}

And UITableViewCell that implements CollectionContainableCell

classEmbedCollectionCell:UITableViewCell,ConfigurableCell,CollectionContainableCell{letcollectionView=UICollectionView()vardisposeBag=DisposeBag()func configure(with viewModel:EmbedCollectionCellViewModel){}overridefunc prepareForReuse(){
super.prepareForReuse()
disposeBag =DisposeBag()}}

For processing events in a nested collection view TableDirector has some methods similar to func cellCreated() (see Events in Cells for details).

director.rx.nestedViewModelSelected(StringCollectionCell.self, in:EmbedCollectionCell.self).subscribe().disposed(by: disposeBag)
director.rx.nestedCellCreated(ButtonCollectionCell.self, in:EmbedCollectionCell.self){ $0.button.rx.tap }.subscribe().disposed(by: disposeBag)
