Does this skill work with GitHub Copilot in VS Code?

Yes, it provides a specific configuration for .vscode/mcp.json to enable the xcode mcpbridge via stdio.

Why does Xcode show a permission dialog repeatedly?

Xcode grants MCP permissions on a per-process (PID) basis. If your MCP client restarts, it receives a new PID, which requires a one-time approval in the Xcode UI.

Why is Cursor rejecting responses from the Xcode MCP bridge?

Cursor is a strict MCP client. Xcode's default mcpbridge may omit required fields. Using the XcodeMCPWrapper proxy resolves these schema violations.

What version of Xcode is required for MCP support?

You must use Xcode 26.3 or later. Additionally, you must enable 'Model Context Protocol' and 'Xcode Tools' within the Xcode Intelligence settings.

How do I target a specific project if I have multiple Xcode windows open?

You can use the 'XcodeListWindows' tool to find the correct tabIdentifier, or set the 'MCP_XCODE_PID' environment variable to target a specific Xcode process.
