# mimeType

The MIME type of the response.

## Declaration

```swift
var mimeType: String? { get }
```

## Discussion

Discussion The MIME type is often provided by the response’s originating source. However, that value may be changed or corrected by a protocol implementation if it can be determined that the response’s source reported the information incorrectly. If the response’s originating source does not provide a MIME type, an attempt to guess the MIME type may be made.
