# Swift package {#swift-package}

If you are working on a Swift package, you can use the
`--replace-scm-with-registry` flag to resolve dependencies from the registry if
they are available:

```bash
swift package --replace-scm-with-registry resolve
```

If you want to ensure that the registry is used every time you resolve
dependencies, you will need to update `dependencies` in your `Package.swift`
file to use the registry identifier instead of a URL. The registry identifier is
always in the form of `{organization}.{repository}`. For example, to use the
registry for the `swift-composable-architecture` package, do the following:
```diff
dependencies: [
-   .package(url: "https://github.com/pointfreeco/swift-composable-architecture", from: "0.1.0")
+   .package(id: "pointfreeco.swift-composable-architecture", from: "0.1.0")
]
```
