What it does

Provides a complete skill for bootstrapping, styling, building, previewing and iterating on native iOS apps using SwiftUI and Xcode 26.3 via the MCP bridge. Includes commands to initialize a project, start an autonomous Ralph OG development loop, apply design systems (glassmorphism, liquid glass, etc.), capture SwiftUI previews, and run builds/tests through MCP tools.

When to use it

Use this skill when you need to quickly scaffold a SwiftUI/Xcode project, run MCP-driven builds and previews, automate an autonomous development loop (Ralph OG) for feature work, or apply consistent design tokens and styles across an iOS app. Ideal for iOS engineers leveraging Claude Code/Xcode MCP integration.

What's included

Scripts: templates and loop scripts for Ralph OG (project init, loop.sh, PROMPT.md) — templates present in repo.
References: design styles, Xcode MCP tool reference, SwiftUI patterns and troubleshooting notes.
Instructions: step-by-step setup for Xcode MCP, commands for init/style/build/preview/status, best practices for MVVM, design tokens, accessibility, and troubleshooting.
