[RxDataSource] Instance method 'items(dataSource:)' requires that 'CollectionViewSectionedDataSource<T>' conform to 'RxCollectionViewDataSourceType’

Instance method 'items(dataSource:)' requires that 'CollectionViewSectionedDataSource' conform to 'RxCollectionViewDataSourceType’

private var dataSource = RxCollectionViewSectionedAnimatedDataSource<ArtistDataModel>(animationConfiguration: AnimationConfiguration(insertAnimation: .none, reloadAnimation: .automatic, deleteAnimation: .none)) { (datasource, collectionView, indexPath, item) in
        guard let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "SelectArtistCollectionViewCell", for: indexPath) as? SelectArtistCollectionViewCell else { return UICollectionViewCell() }
        
        cell.configureCell(item: item)
        return cell

• RxCollectionViewSectionedAnimatedDataSource에 설정한 타입은 ArtistDataModel이다.

struct ArtistDataModel: SectionModelType {

• ArtistDataModel는 SectionModelType을 채택하고 있다.

output.artistList
            .asDriver(onErrorJustReturn: [])
            .drive(artistCollectionView.rx.items(dataSource: dataSource))
            .disposed(by: disposeBag)

// *Instance method 'items(dataSource:)' requires that 'CollectionViewSectionedDataSource<ArtistDataModel>' conform to 'RxCollectionViewDataSourceType’*

• 그러나 서버에서 받아올 당시 ArtistDataModel로 변환해주지 않아서 다음과 같은 오류가 발생 한 것이다.
• Instance method 'items(dataSource:)' requires that 'CollectionViewSectionedDataSource' conform to 'RxCollectionViewDataSourceType’

output.artistList
            .map { [ArtistDataModel(title: "", items: $0)] }
            .asDriver(onErrorJustReturn: [ArtistDataModel(title: "", items: [])])
            .drive(artistCollectionView.rx.items(dataSource: dataSource))
            .disposed(by: disposeBag)

• 다음과 같이 SectionModelType을 채택하고 있던 ArtistDataModel로 변환 바인딩시켜줘야 한다.
