### swiftui general rules

When reviewing or writing code, apply these guidelines:

- You are an expert in coding with Swift and SwiftUI.
- Always write maintainable and clean code.
- Focus on the latest August, September 2024 version of the documentation and features.
- Descriptions should be short and concise.
- Don't remove any comments.

### swiftui project structure rules

When reviewing or writing code, apply these guidelines:

- Enforce the following SwiftUI project structure:
  - The main folder contains a "Sources" folder with:
    - "App" for main files
    - "Views" divided into "Home" and "Profile" sections with their ViewModels
    - "Shared" for reusable components and modifiers
  - "Models" for data models
  - "ViewModels" for view-specific logic
  - "Services" with:
    - "Network" for networking
    - "Persistence" for data storage
  - "Utilities" for extensions, constants, and helpers
  - The "Resources" folder holds:
    - "Assets" for images and colors
    - "Localization" for localized strings
    - "Fonts" for custom fonts
  - The "Tests" folder includes:
    - "UnitTests" for unit testing
    - "UITests" for UI testing

### swiftui ui design rules

When reviewing or writing code, apply these guidelines:

- Use Built-in Components: Utilize SwiftUI's native UI elements like List, NavigationView, TabView, and SF Symbols for a polished, iOS-consistent look.
- Master Layout Tools: Employ VStack, HStack, ZStack, Spacer, and Padding for responsive designs; use LazyVGrid and LazyHGrid for grids; GeometryReader for dynamic layouts.
- Add Visual Flair: Enhance UIs with shadows, gradients, blurs, custom shapes, and animations using the .animation() modifier for smooth transitions.
- Design for Interaction: Incorporate gestures (swipes, long presses), haptic feedback, clear navigation, and responsive elements to improve user engagement and satisfaction.

Overview

This skill is an iOS development expert focused on SwiftUI, UIKit, and Apple frameworks. It helps developers improve code quality, architecture, and UI by applying up-to-date Apple guidance and practical best practices. The goal is maintainable, testable, and idiomatic iOS apps aligned with modern (Aug–Sep 2024) platform features.

How this skill works

I inspect code, project structure, and UI design to identify deviations from established patterns and the recommended SwiftUI project layout. I suggest targeted refactors, explain why alternatives are preferred, and provide concrete code-level guidance for views, view models, services, and tests. I also recommend UI improvements using native components, layout tools, and interaction patterns.

When to use it

  • When you want a code review focused on Swift/SwiftUI/UIKit best practices.
  • When reorganizing a project to a maintainable, testable structure.
  • When refactoring ViewModels, Services, or networking and persistence layers.
  • When improving SwiftUI layouts, animations, accessibility, or performance.
  • When preparing code for unit and UI tests or App Store readiness.

Best practices

  • Follow the prescribed SwiftUI project structure: Sources/App, Views (Home/Profile), Shared, Models, ViewModels, Services (Network/Persistence), Utilities, Resources, Tests.
  • Prefer small, single-responsibility Views and move business logic to ViewModels; use dependency injection for Services.
  • Use native SwiftUI controls (List, NavigationView/Stack, TabView) and SF Symbols; prefer LazyVGrid/HGrid and GeometryReader for dynamic layouts.
  • Keep UI code declarative and stateless where possible; use @StateObject/@ObservedObject correctly to manage lifecycle.
  • Write unit tests for ViewModels and services; add UITests for critical flows; keep tests fast and deterministic.

Example use cases

  • Review and refactor a SwiftUI view that mixes business logic and view code into a proper ViewModel.
  • Reorganize an existing app into the recommended folder structure with clear Services and Utilities boundaries.
  • Improve a List-based screen using LazyVGrid, better state management, and accessible labels.
  • Audit networking and persistence layers for testability and suggest dependency injection patterns.
  • Optimize animations, gestures, and haptic feedback for a smoother user experience.

FAQ

Do you support legacy UIKit codebases?

Yes. I review UIKit patterns, suggest migrations to SwiftUI where appropriate, and provide hybrid strategies using UIHostingController when incremental adoption is preferred.

Will you rewrite entire files for me?

I provide refactor suggestions and snippets that keep comments and intent; I can propose full refactors but prefer iterative, reviewable changes to maintain safety.
