DATASource — 6.1.1

Fixes an issue with the title in the following delegate call, after the Swift 3 migration it returned an array, not it just returns Any?

extension MyController: DATASourceDelegate {
    func dataSource(_ dataSource: DATASource, collectionView: UICollectionView, viewForSupplementaryElementOfKind kind: String, atIndexPath indexPath: IndexPath, withTitle title: Any?) -> UICollectionReusableView? {
        let headerView = collectionView.dequeueReusableSupplementaryView(ofKind: UICollectionElementKindSectionHeader, withReuseIdentifier: TimelineHeaderView.identifier, for: indexPath) as! TimelineHeaderView
        if let title = title as? Date {
            headerView.title = self.dateStringForSectionTitle(title)
        }

        return headerView
    }
}
