# tryToPerform(_:with:)

Dispatches an action message to the specified target.

```
func tryToPerform(_ action: Selector, with object: Any?) -> Bool
```

## Parameters

`action`

The action message you want to dispatch.

`object`

The target object that defines the specified selector.

## Return Value

<doc://com.apple.documentation/documentation/Swift/true> if either the receiver or its delegate can accept the specified selector; otherwise, <doc://com.apple.documentation/documentation/Swift/false>. This method also returns <doc://com.apple.documentation/documentation/Swift/false> if `aSelector` is `nil`.

## Discussion

The receiver tries to perform the method `aSelector` using its inherited [`tryToPerform(_:with:)`](/documentation/AppKit/NSResponder/tryToPerform(_:with:)) method of [`NSResponder`](/documentation/AppKit/NSResponder). If the receiver doesn’t perform `aSelector`, the delegate is given the opportunity to perform it using its inherited <doc://com.apple.documentation/documentation/ObjectiveC/NSObjectProtocol/perform(_:with:)> method of <doc://com.apple.documentation/documentation/ObjectiveC/NSObject-swift.class>.
