Texture ASCollectionDataSourceInterop + Swift

Question

Trying to use ASCollectionDataSourceInterop to combine UICollectionViewCell and ASCellNode in one data source as it is described here

http://texturegroup.org/docs/uicollectionviewinterop.html

However I run into issue here, because

func collectionView(_ collectionView: ASCollectionView, nodeForItemAt indexPath: IndexPath) -> ASCellNode {
        return nil
}

Doesnt work in swift, maybe there is a way to workaround in swift

Answer 1

Found a solution: just make the return type an implicitly unwrapped optional:

func collectionNode(_ collectionNode: ASCollectionNode,
                    nodeBlockForItemAt indexPath: IndexPath) -> ASCellNodeBlock! {
    return optionalNodeBlock
}

The compiler does warn you about the type mismatch, but everything works well
