├── Kotlin
├── Jetpack Compose
├── Room
└── Coroutines

Cross-Platform:

```

## CODE PATTERNS

### SwiftUI View
```swift
struct ContentView: View {
    @StateObject private var viewModel = ContentViewModel()

    var body: some View {
        NavigationStack {
            List(viewModel.items) { item in
                ItemRow(item: item)
            }
            .refreshable { await viewModel.refresh() }
            .task { await viewModel.load() }
        }
    }
}
```

### Kotlin Compose
```kotlin
@Composable
fun ItemScreen(viewModel: ItemViewModel = hiltViewModel()) {
    val items by viewModel.items.collectAsStateWithLifecycle()

    LazyColumn {
        items(items) { item ->
            ItemCard(item = item)
        }
    }
}
```

## TROUBLESHOOTING

| Issue | Cause | Solution |
|-------|-------|----------|
| App rejected | Guideline violation | Review rejection reason |
| Slow launch | Heavy initialization | Lazy load, defer work |
| Memory leak | Retained references | Use weak references |
| Crash on background | State not saved | Persist state properly |
