# viewProvider(for:location:textContainer:)

Returns the text attachment view provider corresponding to the file type.

## Declaration

```swift
func viewProvider(for parentView: UIView?, location: any NSTextLocation, textContainer: NSTextContainer?) -> NSTextAttachmentViewProvider?
```

## Parameters

- `parentView`: The parent view.
- `location`: An doc://com.apple.uikit/documentation/UIKit/NSTextLocation that indicates that start of the string.
- `textContainer`: The doc://com.apple.uikit/documentation/UIKit/NSTextContainer that contains the source text.

## Return Value

Return Value An NSTextAttachmentViewProvider.

## Discussion

Discussion The default implementation queries the text attachment view provider class using the textAttachmentViewProviderClass(forFileType:) method of NSTextAttachment. When non-nil, it instantiates a view, then, fills properties declared in NSTextAttachmentViewProvider if implemented.
