What it does
iOS Architecture is an agent skill from HoangNguyen0403/agent-skills-standard. Apply MVVM, Coordinators, and Clean Architecture (VIP/VIPER) in iOS apps. Use when applying MVVM, Coordinators, or VIP/VIPER architecture in iOS apps.
Its SKILL.md is about 740 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `evals/evals.json` and `references/implementation.md`).
It sits in Mobile, covering iOS development and Design patterns. It works with iOS. The repository describes itself as: A collection of Agent Skills Standard and Best Practice for Programming Languages, Frameworks that help our AI Agent follow best practies on frameworks and programming laguages. The licence is MIT.
When your agent uses it
- VIP/VIPER architecture in iOS apps
- Tasks that involve iOS development
- Tasks that involve Design patterns
Example prompts
- “/ios-architecture”
What it can do on your machine
Read from SKILL.md and the folder at commit b529c2d. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
iOS Architecture loads about 743 tokens when it runs, and up to ~1.2k if it reads all its reference files. Until then it costs about 42 tokens; SKILL.md has 273 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

iOS Architecture Standards
Priority: P0 (CRITICAL)
Implementation Guidelines
MVVM (Model-View-ViewModel)
- ViewModel Responsibility: Handle business logic, formatting, and state. No UIKit imports (except for platform types like
UIImageif strictly necessary). - ViewState: Use single state object or discrete
@Publishedproperties for UI updates. Expose state asprivate(set)or using publishers. - Inputs/Outputs: Define explicit protocols or nested types for inputs (events from View) and outputs (state for View).
Coordinator Pattern
- Navigation Logic: Decouple ViewControllers from navigation logic. Coordinator handles instantiation and push/present. ** NOT use
navigationControllerdirectly in ViewController for screen transitions.** - Dependency Injection: Pass dependencies (Services, Repositories) through Coordinator into ViewModels.
- Child Coordinators: Maintain hierarchy; correctly remove child coordinators from parent's collection when their flow finished.
Clean Architecture (VIP/VIPER)
- VIP (Clean Swift): Use Interactor for logic, Presenter for UI formatting, and ViewController for display.
- Unidirectional Flow: Data flows: View -> Interactor -> Presenter -> View.
- VIPER: (View, Interactor, Presenter, Entity, Router) — another common architectural pattern for iOS apps.
Anti-Patterns
- No Logic in VC: Move business logic to ViewModel/Interactor.
- No Public ViewModel State: Keep state private(set) or using publishers.
- No Direct Navigation: Use Coordinator for screen transitions. Never use
navigationControllerdirectly.
Verification Checklist (Mandatory)
- Pure ViewModel: ViewModel any
UIKitimports? (Prohibited) - Navigation:
navigationControllerused directly in VC for transitions? (Use Coordinator) - State Access: ViewModel state exposed as
public var? (Useprivate(set)or publishers) - Deallocation: child coordinators correctly removed from parent's collection on finish?
- VIP Unidirection: data flow unidirectional (View -> Interactor -> Presenter -> View)?
