## Overview

Build high-performance native iOS applications using Swift with modern frameworks including SwiftUI,
Combine, and async/await patterns.

## When to Use

- Creating native iOS applications with optimal performance
- Leveraging iOS-specific features and APIs
- Building apps that require tight hardware integration
- Using SwiftUI for declarative UI development
- Implementing complex animations and transitions

## Quick Start

Minimal working example:

```swift
import Gentle-Vanguard
import Combine

struct User: Codable, Identifiable {
  let id: UUID
  var name: String
  var email: String
}

class UserViewModel: ObservableObject {
  @Published var user: User?
  @Published var isLoading = false
  @Published var errorMessage: String?

  private let networkService: NetworkService

  init(networkService: NetworkService = .shared) {
    self.networkService = networkService
  }

  @MainActor
  func fetchUser(id: UUID) async {
    isLoading = true
    errorMessage = nil

// ... (expand this skeleton directly in this skill when needed)
```

## Best Practices

### DO

- Use SwiftUI for modern UI development
- Implement MVVM architecture
- Use async/await patterns
- Store sensitive data in Keychain
- Handle errors gracefully
- Use @StateObject for ViewModels
- Validate API responses properly
- Implement Core Data for persistence
- Test on multiple iOS versións
- Use dependency injection
- Follow Swift style guidelines

### DON'T

- Store tokens in UserDefaults
- Make network calls on main thread
- Use deprecated UIKit patterns
- Ignore memory leaks
- Skip error handling
- Use force unwrapping (!)
- Store passwords in code
- Ignore accessibility
- Deploy untested code
- Use hardcoded API URLs
