Issues when a folder contains multiple Swift packages

[svanimpe]

To Reproduce

Steps to reproduce the behavior (in an empty directory):

mkdir first && cd first && swift package init --type executable
cd ..
mkdir second && cd second && swift package init --type executable
cd ..
code .

In other words, create a project structure like this, then open it in VS Code:

.
├── first
│   ├── Package.swift
│   └── Sources
│       └── main.swift
└── second
    ├── Package.swift
    └── Sources
        └── main.swift

Issues

Open a Package.swift file. When using Swift 5.9, features such as autocompletion don't work in this file. With Swift 6.0, I get the following additional error:

Workaround

Open first or second separately in VS Code. Everything works fine then.

Environment

• macOS 13.6
• swift-6.0-DEVELOPMENT-SNAPSHOT-2024-04-22-a
• Visual Studio Code version: 1.88.1
• vscode-swift version: 1.9.0

This seems to be a general issue with Swift packages in a subfolder, not just folders that contain multiple packages. I also have this issue in directories that contain, for example, one Swift package, and one NPM project.

@svanimpe I think this is another sourcekit-lsp issue. It looks like it has been around for a while, but without the underlined import

I've added apple/sourcekit-lsp#1210

Thanks Adam!

@svanimpe just curious, does it work if you setup a multi-root workspace (https://code.visualstudio.com/docs/editor/workspaces#_multiroot-workspaces) which contains the various folders?
