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.
npx agentmods add rules/brunogama/ios-cursor-rules/with-iosgit clone --depth 1 https://github.com/brunogama/ios-cursor-rulesWhat 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 | $0.00000 | $0.02404 |
| Opus 5 | $0.00000 | $0.01202 |
| Sonnet 5 | $0.00000 | $0.00481 |
| Haiku 4.5 | $0.00000 | $0.00240 |
Grade A, and why
with-ios 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 3d 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 — 358 lines — stays where its author put it; the contents beside it link to each section on GitHub.
iOS Development Best Practices
As an AI assistant working on iOS applications, I should follow these guidelines to ensure high-quality, user-friendly, and efficient iOS apps.
iOS App Architecture
Architecture Patterns
-
Use appropriate architecture patterns based on app complexity:
- MVC: Simple apps or when following Apple's basic patterns
- MVVM: Medium complexity apps, works well with SwiftUI/Combine
- VIPER/Clean: Complex apps requiring clear separation of concerns
- Composable Architecture: Advanced reactive apps with predictable state management
-
Keep view controllers/views lightweight by moving business logic to separate components
-
Use coordinator pattern for complex navigation flows
-
Consider feature-based modularization for large applications
Project Organization
- Organize project by feature, not by type
- Use Swift packages to modularize components
- Group related files in logical folders
- Utilize Xcode's project navigator groups to maintain code organization

UIKit vs SwiftUI
When to Use UIKit
- When targeting iOS 12 or earlier
- For complex custom UI that's difficult to implement in SwiftUI
- When you need precise control over UI performance optimization
- For apps heavily dependent on UIKit-specific features
When to Use SwiftUI
- For new apps targeting iOS 14+
- For rapid development and prototyping
- When you want to share UI code across Apple platforms
- For list-based interfaces and standard UI components
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.

with-ios is a cursor rule published in the GitHub repository brunogama/ios-cursor-rules (74 stars, last pushed 1y ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 2,404 tokens. 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 2026-08-30.
