Xcode MCP Tool Workflows

Core principle: Xcode MCP gives you programmatic IDE access. Use workflow loops, not isolated tool calls.

Window Targeting (Critical Foundation)

Most tools require a tabIdentifier. Always call XcodeListWindows first.

1. XcodeListWindows → list of (tabIdentifier, workspacePath) pairs
2. Match workspacePath to your project
3. Use that tabIdentifier for all subsequent tool calls

Cache the mapping for the session. Only re-fetch if:

• A tool call fails with an invalid tab identifier
• You opened/closed Xcode windows
• You switched projects
