# setReceiversSpecifier(_:)

Sets the receiver’s object specifier.

```
func setReceiversSpecifier(_ receiversRef: NSScriptObjectSpecifier?)
```

## Parameters

`receiversRef`

The receiver’s object specifier.

## Discussion

When the command is executed, it sets attributes or relationships in the objects specified by `receiversRef`.

This method overrides [`receiversSpecifier`](/documentation/Foundation/NSScriptCommand/receiversSpecifier) in [`NSScriptCommand`](/documentation/Foundation/NSScriptCommand). It performs the same function as the overridden method, with a critical difference: it causes the container specifier part of the passed-in object specifier to become the receiver specifier of the command, and the key part of the passed-in object specifier to become the key specifier. If, for example, `receiversRef` is a specifier for `the color of the third rectangle`, the receiver specifier is `the third rectangle,` while the key specifier is `the color`.
