A first-pass app-building guide that creates every screen and navigation path with placeholder content.

Use it after creating an Xcode project to set up SwiftUI views, tabs, navigation stacks, folders, and tappable screen flows.

It gives a new app a complete structure to test before real data, styling, and storage are added.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00068	$0.01100
Opus 5.5	$0.00027	$0.00440
Sonnet 5.5	$0.00014	$0.00220
Haiku 4.5	$0.00007	$0.00110

Security

Grade A, and why

scaffolding scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 123 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Scaffolding

Build the entire app structure in one pass. Every screen, every navigation path, placeholder content everywhere. No detail, no styling, no data. Just the bones.

When to Use

You just created your Xcode project and dropped in CLAUDE.md + APP_SPEC.md
You're starting a fresh rebuild of an existing app
You have your spec and are ready for the first Claude Code session

Prerequisites

Xcode project created (File > New > App, SwiftUI, SwiftData)
CLAUDE.md in project root
APP_SPEC.md in project root
Git initialized, initial commit made
Claude Code running in the project directory

The Prompt

One prompt. One session. One output.

Read CLAUDE.md and APP_SPEC.md. Build the full app skeleton.

Every screen from the spec should exist as a SwiftUI view with
placeholder content. Set up the tab navigation (if applicable),
NavigationStacks, and all navigation paths between screens.

No real data. No styling. No custom components. No persistence.
Just the structure so I can tap through every screen in the simulator.

Create the file structure defined in CLAUDE.md. Each view goes
in the correct directory.

What Claude Code Should Produce

File Structure

[AppName]/
├── [AppName]App.swift          (entry point with tab view or root navigation)
├── ContentView.swift           (root view with tab bar or initial navigation)

│   └── Settings/

└── Assets.xcassets/

Each View Should Contain

A NavigationStack wrapper (if it's a root tab view)
Placeholder text: "Projects Home" or "Settings will go here"
Navigation links/sheets wired to their destinations with placeholder triggers
The correct toolbar items (even if they're just Text placeholders)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

scaffolding is a skill published in the GitHub repository troyjthomas/ios-agent-skills (2 stars, last pushed 5mo ago), licensed MIT. It adds 68 tokens to every session and 1,100 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
