What is the primary purpose of the Xcode MCP Reference skill?

It provides Claude with the exact syntax and parameter requirements needed to control Xcode through the Model Context Protocol, enabling tasks like file editing, building, and testing.

How does this help with debugging?

It provides access to XcodeListNavigatorIssues and GetBuildLog, allowing Claude to see structured error data exactly as it appears in the Xcode Issue Navigator.

Why is XcodeListWindows the most important tool in this set?

Most Xcode MCP tools require a 'tabIdentifier' to function. XcodeListWindows is the discovery tool that provides this identifier for active project windows.

Does this skill support SwiftUI development?

Yes, it includes documentation for the RenderPreview tool, which allows Claude to render SwiftUI #Preview blocks as images for visual verification.

Can Claude edit existing Swift files using these tools?

Yes, the reference includes documentation for XcodeUpdate, which allows Claude to apply precise, str_replace-style patches to existing source code.
