# cellClass

The subclass of [`NSCell`](/documentation/AppKit/NSCell) that the matrix uses when creating new (empty) cells.

```
var cellClass: AnyClass { get set }
```

## Discussion

The value of this property should be the id of a subclass of [`NSCell`](/documentation/AppKit/NSCell), which can be obtained by sending the `class` message to either the [`NSCell`](/documentation/AppKit/NSCell) subclass object or to an instance of that subclass. The default cell class is that set with the class method `setCellClass(_:)`, or [`NSActionCell`](/documentation/AppKit/NSActionCell) if no other default cell class has been specified.

You need to use this property only with matrices initialized with [`init(frame:)`](/documentation/AppKit/NSMatrix/init(frame:)), because the other initializers allow you to specify an instance-specific cell class or cell prototype.
