## Push Notifications

### Setup
```swift
// Request authorization
UNUserNotificationCenter.current().requestAuthorization(
    options: [.alert, .badge, .sound]
) { granted, error in
    if granted {
        DispatchQueue.main.async {
            UIApplication.shared.registerForRemoteNotifications()
        }
    }
}
```

### Rich Notifications
```swift
// Notification Service Extension
class NotificationService: UNNotificationServiceExtension {
    override func didReceive(
        _ request: UNNotificationRequest,
        withContentHandler contentHandler: @escaping (UNNotificationContent) -> Void
    ) {
        // Modify notification content
        let content = request.content.mutableCopy() as! UNMutableNotificationContent
        // Add attachments, modify content
        contentHandler(content)
    }
}
```

## Widgets & Live Activities

### Widget Implementation
```swift
struct MyWidget: Widget {
    var body: some WidgetConfiguration {
        StaticConfiguration(
            kind: "MyWidget",
            provider: Provider()
        ) { entry in
            MyWidgetView(entry: entry)
        }
        .configurationDisplayName("My Widget")
        .description("Widget description")
        .supportedFamilies([.systemSmall, .systemMedium])
    }
}
```

### Live Activities
```swift
struct DeliveryAttributes: ActivityAttributes {
    struct ContentState: Codable, Hashable {
        var status: String
        var estimatedTime: Date
    }

    var orderNumber: String
}

// Start activity
let attributes = DeliveryAttributes(orderNumber: "12345")
let state = DeliveryAttributes.ContentState(
    status: "Preparing",
    estimatedTime: .now.addingTimeInterval(3600)
)
let activity = try Activity.request(
    attributes: attributes,
    content: .init(state: state, staleDate: nil)
)
```

## App Intents (Shortcuts)

```swift
struct OrderCoffeeIntent: AppIntent {
    static var title: LocalizedStringResource = "Order Coffee"
    static var description = IntentDescription("Order your favorite coffee")

    @Parameter(title: "Coffee Type")
    var coffeeType: CoffeeType

    @Parameter(title: "Size")
    var size: CoffeeSize

    func perform() async throws -> some IntentResult {
        let order = try await OrderService.place(
            type: coffeeType,
            size: size
        )
        return .result(value: "Order #\(order.id) placed!")
    }
}

// App Shortcuts Provider
struct MyAppShortcuts: AppShortcutsProvider {
    static var appShortcuts: [AppShortcut] {
        AppShortcut(
            intent: OrderCoffeeIntent(),
            phrases: ["Order coffee from \(.applicationName)"]
        )
    }
}
```

## Background Processing

### Background Tasks
```swift
// Register
BGTaskScheduler.shared.register(
    forTaskWithIdentifier: "com.app.refresh",
    using: nil
) { task in
    handleAppRefresh(task: task as! BGAppRefreshTask)
}

// Schedule
let request = BGAppRefreshTaskRequest(identifier: "com.app.refresh")
request.earliestBeginDate = Date(timeIntervalSinceNow: 3600)
try BGTaskScheduler.shared.submit(request)
```

### Background URL Session
```swift
let config = URLSessionConfiguration.background(
    withIdentifier: "com.app.download"
)
config.isDiscretionary = true
config.sessionSendsLaunchEvents = true

let session = URLSession(configuration: config, delegate: self, delegateQueue: nil)
let task = session.downloadTask(with: url)
task.resume()
```

## Platform Availability

```swift
// Check API availability
if #available(iOS 17, macOS 14, *) {
    // Use new API
} else {
    // Fallback
}

// Platform-specific code
#if os(iOS)
import UIKit
#elseif os(macOS)
import AppKit
#endif

// Check device capabilities
#if targetEnvironment(simulator)
// Simulator-specific code
#endif
```

## Best Practices

1. **Check availability** - Guard new API usage
2. **Request permissions gracefully** - Explain why
3. **Handle permission denial** - Provide alternatives
4. **Test on real devices** - Many features require hardware
5. **Background wisely** - Battery impact matters
6. **Privacy first** - Minimize data collection
7. **Graceful degradation** - Work without optional features

Integrate deeply, but respect user choice.
