|

```

`DiffableDataSource.CollectionView` fully handles the reload animations.

The `DiffableDataSource.TableViewAdapterAdapter` serves as a `UITableViewDataSource` that handles `ListPublisher` snapshots for a `UITableView`. Subclasses of `DiffableDataSource.TableViewAdapter` may override some `UITableViewDataSource` methods as needed.
|
||||
The `DiffableDataSource.TableViewAdapterAdapter` instance needs to be held on (retained) for as long as the `UITableView`'s lifecycle.
|

```

self.dataSource = DiffableDataSource.TableViewAdapter<Person>(

cell.setPerson(person)

The dataSource can then apply changes from a `ListPublisher` as shown:
|

```
|

listPublisher.addObserver(self) { [weak self] (listPublisher) in
|

self?.dataSource?.apply(
|

listPublisher.snapshot,
|

animatingDifferences: true
|

)
|
||||
}
|
||||
```
|

`DiffableDataSource.TableViewAdapter` fully handles the reload animations.
