# exifData

Identifies an NSDictionary object containing the EXIF data for the image.

## Declaration

```swift
static let exifData: NSBitmapImageRep.PropertyKey
```

## Discussion

Discussion This property is used only when reading or writing JPEG files. The dictionary contains the EXIF keys and values. The standard dictionary keys (that is, those that are not specific to camera vendors) are identical to those for kCGImagePropertyExifDictionary declared in the CGImageSource API. See kCGImagePropertyExifDictionary Keys for details.
