# performClose(_:)

Attempts to close the popover.

## Declaration

```swift
@IBAction func performClose(_ sender: Any?)
```

## Parameters

- `sender`: The sender of the action message.

## Discussion

Discussion The popover will not be closed if it has a delegate and the delegate implements the returns popoverShouldClose(_:) method returning false, or if a subclass of the NSPopover class implements popoverShouldClose: and returns false). The operation will fail if the popover is displaying a nested popover or if it has a child window. A window will attempt to close its popovers when it receives a performClose(_:) message. The popover animates out when closed unless the animates property is set to false.
