Complete Claude Code setup guide for iOS/Swift development - Extended thinking, XcodeBuildMCP, PRD workflows, and starter kit

I've been using Claude Code for iOS development and put together a comprehensive guide covering all the features with iOS-specific configurations. **Key sections:** 📱 **iOS-Specific Setup** * CLAUDE.md templates for Swift/SwiftUI projects * XcodeBuildMCP integration (build, test, run simulator from Claude Code) * Custom slash commands for iOS workflows 🧠 **Extended Thinking Deep Dive** * Token budgets: `think` (4K) → `ultrathink` (32K) * When to use each level * Cost estimates per task * Tab to toggle, Ctrl+O to see thinking 📋 **PRD-Driven Development** * Full workflow from requirements to implementation * Spec and task templates * Commands: `/create-prd`, `/generate-spec`, `/implement-feature` 🔒 **Sandbox Mode** * Read-only exploration that still allows Xcode builds and simulator * Graduated permission levels * Great for learning or code review 🛠️ **New Features Covered** * Agent Skills (model-invoked capabilities) * Output Styles (teaching mode) * Plugins system * Hooks (PreToolUse, PostToolUse, SessionStart, etc.) * MCP scopes and environment variable expansion **Includes a starter kit** with pre-configured commands, subagents, skills, hooks, and templates. **GitHub:** [https://github.com/keskinonur/claude-code-ios-dev-guide](https://github.com/keskinonur/claude-code-ios-dev-guide) Happy to answer questions if anyone's getting started with Claude Code for mobile dev!
