What is SwiftUIAgentToolkit CLAUDE.md?

A project instruction file for building iOS apps with SwiftUI, Apple's framework for app interfaces. It defines the project's architecture, coding rules, naming, and testing practices.

Starting SwiftUI projects and guiding work on views, view models, models, asynchronous code, previews, builds, and tests.

It gives coding agents consistent rules to follow when changing the app.

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	$0.00681	$0.00681
Opus 5.5	$0.00272	$0.00272
Sonnet 5.5	$0.00136	$0.00136
Haiku 4.5	$0.00068	$0.00068

Security

Grade A, and why

SwiftUIAgentToolkit CLAUDE.md 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 2mo 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 — 58 lines — stays where its author put it; the contents beside it link to each section on GitHub.

SwiftUIAgentToolkit

A toolkit for bootstrapping SwiftUI mobile apps — designed for rapid, vibe-coded development.

Project Purpose

A cloneable template for quickly starting new iOS apps with SwiftUI. See docs/SETUP.md for how to create an Xcode project inside this template.

Architecture

Swift 5.9+ / SwiftUI — No UIKit unless absolutely necessary
Minimum deployment target: iOS 18+
Architecture pattern: MVVM with @Observable macro (not ObservableObject)

Coding Standards

Use @Observable instead of ObservableObject / @StateObject
Prefer @State for local view state, @Environment for dependency injection
Extract reusable views into their own files — one view per file
Use #Preview macro for previews, not PreviewProvider
No force unwraps (!) — use guard let, if let, or provide defaults
Async/await for all async work; no callbacks or Combine unless integrating external APIs

Naming Conventions

Views: FooView.swift (e.g., HomeView, ProfileView)
ViewModels: FooViewModel.swift
Models: Foo.swift (plain struct/class names)
Extensions: Foo+Bar.swift (e.g., Color+Brand.swift)

Build & Test

Three commands are available for verifying app correctness after code changes. They are provided by the ios-verify-ui plugin — install it with:

claude plugin add https://github.com/vivqu/claude-swift-verify-ui-plugin

/ios-verify-ui:verify-ui — Build and run the app on a simulator, take a screenshot, and confirm UI changes look correct. Use after any visual change.
/ios-verify-ui:verify-test — Run the unit and UI test suite and report pass/fail results. Use after adding or changing logic with tests.
/ios-verify-ui:verify — Full verification: runs both UI and test checks in sequence and reports a combined summary. Use when you want to confirm everything is working end to end.

Prototyping

When building prototype screens that need images, use the /placeholder-ui skill. It provides:

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.
