Hi @YunyueLin , What is type of viewModel.models? I have seen this error when I made binding with wrong Observable type and collectionView.rx.items.

[YunyueLin]

Hi @tarunon in the VM let models = Variable<[FabricDataModel]>([]) .

and in the V. let dataSource = RxCollectionViewSectionedReloadDataSource<SectionModel<String,FabricDataModel>>

[tarunon]

Hmm, could you please change models type as Variable<[SectionModel<String, FabricDataModel>]> ?

...thanks.
