# checksum

The checksum for the archive file that contains the referenced binary artifact.

## Declaration

```swift
final var checksum: String?
```

## Discussion

Discussion If you make a remote binary framework available as a Swift package, declare a remote, or URL-based, binary target in your package manifest with binaryTarget(name:url:checksum:). Always run swift package compute-checksum path/to/MyFramework.zip at the command line to make sure you create a correct SHA256 checksum. For more information, see Distributing binary frameworks as Swift packages.
