Same problem here:
The view returned from -collectionView:viewForSupplementaryElementOfKind:atIndexPath: does not match the element kind it is being used for. When asked for a view of element kind 'UICollectionElementKindSectionHeader' the data source dequeued a view registered for the element kind 'UICollectionElementKindSectionFooter
