# textView(_:urlForContentsOf:at:)

Returns a URL representing the document contents for a text attachment.

## Declaration

```swift
@MainActor optional func textView(_ textView: NSTextView, urlForContentsOf textAttachment: NSTextAttachment, at charIndex: Int) -> URL?
```

## Parameters

- `textView`: The text view sending the message.
- `textAttachment`: The text attachment object containing an NSFileWrapper object that holds the contents of the attached file.
- `charIndex`: The character index of the text attachment.

## Return Value

Return Value The absolute URL for the document contents represented by textAttachment.

## Discussion

Discussion The returned NSURL object is used by the text view to provide default behaviors involving text attachments such as Quick Look and double-clicking. For example, the NSTextView method quickLookPreviewableItems(inRanges:) uses this method for mapping text attachments to their corresponding document URLs, and NSTextView invokes the NSWorkspace method open(_:) with the URL returned from this method when the delegate has no textView(_:doubleClickedOn:in:at:) implementation.
