# autosave(withDelegate:didAutosave:contextInfo:)

Autosaves the document’s contents to an appropriate location in the file system.

## Declaration

```swift
func autosave(withDelegate delegate: Any?, didAutosave didAutosaveSelector: Selector?, contextInfo: UnsafeMutableRawPointer?)
```

## Parameters

- `delegate`: The delegate to which the selector message is sent.
- `didAutosaveSelector`: The selector of the message sent to the delegate.
- `contextInfo`: Object passed with the callback to provide any additional context information.

## Discussion

Discussion After autosaving, sends the message selected by didAutosaveSelector to the delegate, with contextInfo as the last argument. The method selected by didAutosaveSelector must have the same signature as: - (void)document:(NSDocument *)document didAutosave:(BOOL)didAutosaveSuccessfully contextInfo:(void *)contextInfo If an error occurs while autosaving, the method reports it to the user before sending the delegate a succeeded:NO message.
