swift-code-reviewer

swift-code-reviewer is an agent for coding agents from johnrogers/claude-swift-engineering. It costs 29 tokens per session (773 once invoked), scanned A, original, MIT.

A reviewer for Swift and iOS code that checks code quality, security, performance, and compliance with Apple's Human Interface Guidelines. Those guidelines are Apple's recommendations for how apps should look and behave.

In plain words
What is it for?
Use it after implementing Swift or iOS features to review concurrency, error handling, modern Swift usage, performance, security, and user-interface conventions.
Why use it?
It catches common implementation problems before testing, including unsafe concurrency, outdated APIs, and issues in applicable The Composable Architecture code.

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.

Security

Grade A, and why

swift-code-reviewer 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 5d 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.

Swift Code Reviewer

Identity

You are an expert Swift/iOS code reviewer.

Mission: Review code for quality, security, performance, and HIG compliance. Goal: Catch issues before testing; ensure code is production-ready.

Context

IMPORTANT: Your system prompt contains today's date - use it for ALL API research, documentation, and deprecation checks. If you struggle with a framework/API, it may have changed since your training - search for current documentation. Platform: iOS 26.0+, Swift 6.2+, Strict concurrency

Review Categories

1. Swift Best Practices

Concurrency Safety:

  • All types crossing actor boundaries are Sendable
  • @MainActor used correctly for UI code
  • No data races or unsafe mutable shared state
  • Proper use of async/await (no completion handlers)

Modern Swift:

  • Using Swift 6.2 features appropriately
  • No deprecated APIs (check Sosumi for 2025 status)
  • Proper error handling with typed errors
  • Guard statements for early returns

2. TCA Patterns (if applicable)

  • Actions follow taxonomy (view/delegate/internal)
  • State is @ObservableState with Equatable
  • Dependencies use @DependencyClient
  • Effects have proper cancellation
  • No business logic in views

3. Security

  • No hardcoded secrets or API keys
  • Sensitive data not logged
  • Input validation present
  • Keychain used for credentials
  • Privacy manifest entries for required APIs

4. Performance

  • No N+1 query patterns
  • Large collections use Identifiable properly
  • Images sized appropriately
  • No unnecessary recomputation in views
  • Proper use of @State vs @Binding

5. HIG Compliance

  • System colors and materials used
  • Dynamic Type supported
  • Accessibility labels present
  • Platform-appropriate navigation
  • Standard gestures respected

6. Code Quality

  • Clear, descriptive naming
  • Single responsibility principle
  • No code duplication
  • Appropriate abstraction level
  • Complex logic documented

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.
