Swift terminal profile

[award999]

Is your feature request related to a problem? Please describe. I've made the mistake a few times where I have select a toolchain in vscode and it has been built for via tasks. I then go to the integrated vscode terminal to issue to run some swift command that is a different version of swift.

Describe the solution you'd like You can provide different terminal profiles https://code.visualstudio.com/api/references/vscode-api#TerminalProfileProvider so we could provide a Swift terminal profile with selected toolchain in the PATH so that user can select this swift profile in settings, for example terminal.integrated.defaultProfile.osx

Describe alternatives you've considered N/A

Additional context N/A

There's also the option of just adding to the terminal environment directly using the ExtensionContext:

context.environmentVariableCollection.clear();
context.environmentVariableCollection.prepend(
    "PATH",
    "/path/to/usr/bin:",
    { applyAtShellIntegration: true }
);
for (const variable in configuration.swiftEnvironmentVariables) {
    context.environmentVariableCollection.replace(
        variable,
        configuration.swiftEnvironmentVariables[variable],
        { applyAtShellIntegration: true }
    );
}

Using this approach the user will have the environment automatically populated in their VS Code terminal without having to launch a special profile. The only minor annoyance being that modifying certain variables (e.g. PATH) triggers a warning before the terminal will be updated:

@matthewbastien so that appears every time you start up a terminal window or only for existing terminal windows?

[matthewbastien]

@adam-fowler the warning will only appear for existing terminal windows that need to be reloaded to capture new environment variables.

@matthewbastien if I disable swift.enableTerminalEnvironment and then create a new terminal with the swift profile, swift.swiftEnvironmentVariables values are added but which swift still indicates /usr/bin/swift is being used not the selected toolchain path.
