# Generated project with the Xcode package integration {#generated-project-with-xcode-based-integration}

If you are using the <.localized_link href="/guides/features/projects/dependencies#xcodes-default-integration">Xcode's default integration</.localized_link> of packages with Tuist Projects, you need to use the registry identifier instead of a URL when adding a package:
```swift
import ProjectDescription

let project = Project(
    name: "MyProject",
    packages: [
        // Source control resolution
        // .package(url: "https://github.com/pointfreeco/swift-composable-architecture", from: "0.1.0")
        // Registry resolution
        .package(id: "pointfreeco.swift-composable-architecture", from: "0.1.0")
    ],
    targets: [
        .target(
            name: "App",
            product: .app,
            bundleId: "dev.tuist.App",
            dependencies: [
                .package(product: "ComposableArchitecture"),
            ]
        )
    ]
)
```

> [!TIP]
> You don't have to add every package by its registry identifier. Running `tuist registry setup` once the project has been generated also configures Xcode to resolve packages that are declared with a source control URL from the registry, which `registryEnabled` doesn't do on its own. See <.localized_link href="/guides/features/registry/xcode-project#resolving-source-control-packages">Resolving source control packages</.localized_link>.

Generated project with the Xcode package integration

If you are using the Xcode's default integration of packages with Tuist Projects, you need to use the registry identifier instead of a URL when adding a package:

swift

import ProjectDescription

let project = Project(
    name: "MyProject",
    packages: [
        // Source control resolution
        // .package(url: "https://github.com/pointfreeco/swift-composable-architecture", from: "0.1.0")
        // Registry resolution
        .package(id: "pointfreeco.swift-composable-architecture", from: "0.1.0")
    ],
    targets: [
        .target(
            name: "App",
            product: .app,
            bundleId: "dev.tuist.App",
            dependencies: [
                .package(product: "ComposableArchitecture"),
            ]
        )
    ]
)

Tip

You don't have to add every package by its registry identifier. Running tuist registry setup once the project has been generated also configures Xcode to resolve packages that are declared with a source control URL from the registry, which registryEnabled doesn't do on its own.
