# reuseIdentifier

A string for identifying a reusable cell.

```
var reuseIdentifier: String? { get }
```

## Discussion

The reuse identifier is associated with a [`UITableViewCell`](/documentation/UIKit/UITableViewCell) object that the table-view’s delegate creates with the intent to reuse it as the basis (for performance reasons) for multiple rows of a table view. It is assigned to the cell object in [`initWithFrame:reuseIdentifier:`](/documentation/UIKit/UITableViewCell/initWithFrame:reuseIdentifier:) and cannot be changed thereafter. A [`UITableView`](/documentation/UIKit/UITableView) object maintains a queue (or list) of the currently reusable cells, each with its own reuse identifier, and makes them available to the delegate in the [`dequeueReusableCell(withIdentifier:)`](/documentation/UIKit/UITableView/dequeueReusableCell(withIdentifier:)) method.
