Custom toolchain path does not exist in dev containers

[MahdiBM]

Describe the bug
Getting:

The Swift executable at "/Applications/Xcode 16.2.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin" either could not be found or failed to launch. Please select a new toolchain.

Which is correct since I'm in a dev container. Though the extension could perhaps do something so this doesn't happen.

To Reproduce
Set a custom toolchain path then open the project in a dev container.

Expected behavior
No conflicts / failures when switching to a dev container.

Environment

• Swift version: 6.0.3 RELEASE
• Visual Studio Code version: 1.11.4

Additional context
Add any other context about the problem here.

You should be able to modify your devcontainer.json to add settings that are only applied inside the dev container. In this case you can add the swift.path setting under customizations.vscode.settings inside devcontainer.json to set the Swift path back to where Swift lives in the container.

    "customizations": {
        "vscode": {
            "settings": {
                "swift.path": "/usr/bin"
            },
            "extensions": [
                "sswg.swift-lang"
            ]
        }
    }

@MahdiBM does that suggestion fix your problem?

[MahdiBM]

It does, but I wonder if we should stop here or not.
For example maybe it is appropriate for the extension to be smart about this and detect the situation and let the user know what to do.
