Suports Xcode projects and Swift packages.
This commit refactors the SwiftLanguageAdapter to discover dependencies in Swift projects without requiring the Swift toolchain to be installed. - For Xcode projects, the adapter now uses the @bacons/xcode npm package to parse the project.pbxproj file directly, instead of shelling out to xcodebuild. This allows for the discovery of both local and remote package dependencies in a more robust and environment-independent way. - For SwiftPM projects, the adapter now uses a regular expression to parse Package.swift files and extract dependencies. This 'good enough' approach avoids the need to shell out to swift package dump-package. - The DerivedData path is now configurable, and the adapter will perform a targeted search for downloaded packages within it, improving performance. - The tests have been updated to use a mock DerivedData folder and a realistic test fixture, ensuring that the new implementation is well-tested and isolated from the user's local environment.

Approved with a comment about docs location - have you tested this out to ensure it's working as expected?

Yep - it does. Gemini CLI was able to one-shot a chat app based on a Swift SDK with (Gemini-generated) Dotguides files: The same without any context files, but trying to prod the agent to use the (already installed) library: I am actually impressed. |

This PR introduces support for discovering dependencies in Swift projects, including both Swift Packages and Xcode Projects.
A new
SwiftLanguageAdapterhas been implemented to handle the discovery logic.Swift Package Manager Projects
For projects with a
Package.swiftfile, the adapter shells out toswift package show-dependenciesto resolve and identify all package dependencies.Xcode Projects
For Xcode projects (
.xcodeprojfiles), the adapter usesxcodebuild -resolvePackageDependenciesto resolve the package graph. The output of this command is then parsed to discover both:This requires the Swift Toolchain to be installed.
Testing
Unit tests have been added to validate the new discovery logic for both project types, including tests for projects with local package dependencies.
