Setting Up Xcode Claude Code with Third-Party API Endpoints

This guide explains how to configure Xcode's built-in Claude Code integration to work with third-party API endpoints instead of the official Anthropic API.

Step 1: Bypass the Authentication UI

Xcode normally requires signing in through the UI with an Anthropic account or API key and doesn't offer any bypass. Even if the Xcode internal claude can use your third-party endpoint Xcode won't send any query because YoU ARe NOt LOgGeD IN. To bypass this when using a third-party endpoint, set a placeholder API key override, which you cannot do through the UI:

defaults write com.apple.dt.Xcode IDEChatClaudeAgentAPIKeyOverride ' '

A composable pattern for pure state machines with effects

State machines are everywhere in interactive systems, but they're rarely defined clearly and explicitly. Given some big blob of code including implicit state machines, which transitions are possible and under what conditions? What effects take place on what transitions?

There are existing design patterns for state machines, but all the patterns I've seen complect side effects with the structure of the state machine itself. Instances of these patterns are difficult to test without mocking, and they end up with more dependencies. Worse, the classic patterns compose poorly: hierarchical state machines are typically not straightforward extensions. The functional programming world has solutions, but they don't transpose neatly enough to be broadly usable in mainstream languages.

Here I present a composable pattern for pure state machiness with effects,

	#
	# Moving a file in git doesn't track history, so the purpose of this
	# utility is best explained from the kernel wiki:
	#
	# Git has a rename command git mv, but that is just for convenience.
	# The effect is indistinguishable from removing the file and adding another
	# with different name and the same content.
