# parameters

The action’s parameters.

## Declaration

```swift
var parameters: NSMutableDictionary? { get set }
```

## Discussion

Discussion The parameters of an action reflect the choices made and values entered in the action’s user interface. Keys in the parameters dictionary identify specific user-interface objects. If an action uses the Cocoa bindings mechanism, the parameters of an AMBundleAction object are automatically set.
