+Alternatively you can use the ``UICollectionViewDiffableDataSource`` and ``UITableViewDiffableDataSource`` initializers:

+let dataSource = UITableViewDiffableDataSource(tableView: myTableView, cellRegistration: cellRegistration)

+## UITableView Header/Footer View Registration
+
+A registration for the table view’s header/footer views.
+
+```swift
+let sectionViewRegistration = UITableView.SectionViewRegistration<UITableViewHeaderFooterView, String> {

+     
+    var configuration = sectionView.defaultContentConfiguration()
+    configuration.text = string

+}

+     
+After you create a section view registration, you pass it in to ``dequeueConfiguredReusableSectionView(using:section:)``, which you call from your data source’s section header view provider.
+
+```swift
+dataSource.headerViewProvider = { tableView, section in
+    return tableView.dequeueConfiguredReusableSectionView(using: sectionViewRegistration, section: section)
+}
+```
+
+You can also ``applyHeaderViewRegistration()`` and `applyFooterViewRegistration()``:
+
+```swift
+dataSource.applyHeaderViewRegistration(sectionViewRegistration)

+
+## Diffable DataSource Snapshot Apply Options
+
+Options for applying snapshots to a diffable datasource:
+
+```swift
+// Applies the snapshot animated with default animation duration.
+dataSource.apply(mySnapshot, .animated)
+
+// Applies the snapshot animated with the specified animation duration.
+dataSource.apply(mySnapshot, .animated(duration: 2.0))
+
+// Applies the snapshot non animated.
+dataSource.apply(mySnapshot, .withoutAnimation)
+
+// Applies the snapshot using reload data.
+dataSource.apply(mySnapshot, .usingReloadData)
+```
