# hide(_:)

Hides all the receiver’s windows, and the next app in line is activated.

```
func hide(_ sender: Any?)
```

## Parameters

`sender`

The object that sent the command.

## Discussion

This method is usually invoked when the user chooses Hide in the app’s main menu. When this method begins, it posts an [`willHideNotification`](/documentation/AppKit/NSApplication/willHideNotification) to the default notification center. When it completes successfully, it posts an [`didHideNotification`](/documentation/AppKit/NSApplication/didHideNotification).
