🔧 Modern Development Patterns

Concurrency with Swift 6

// Data race safety by default
actor DataStore {
    private var items: [String] = []
    
    func add(_ item: String) {
        items.append(item)
    }
    
    func getItems() -> [String] {
        return items
    }
}

// Usage
let store = DataStore()
await store.add("New Item")
let items = await store.getItems()

SwiftUI with Observation

import SwiftUI
import Observation

@Observable
class AppModel {
    var items: [Item] = []
    var isLoading = false
    
    func loadItems() async {
        isLoading = true
        defer { isLoading = false }
        
        // Simulate network call
        try? await Task.sleep(for: .seconds(1))
        items = [Item(name: "Sample Item")]
    }
}

struct ContentView: View {
    @State private var model = AppModel()
    
    var body: some View {
        NavigationView {
            List(model.items) { item in
                Text(item.name)
            }
            .navigationTitle("Items")
            .task {
                await model.loadItems()
            }
            .overlay {
                if model.isLoading {
                    ProgressView()
                }
            }
        }
    }
}

struct Item: Identifiable {
    let id = UUID()
    let name: String
}

App Intents Integration

import AppIntents

struct AddItemIntent: AppIntent {
    static var title: LocalizedStringResource = "Add Item"
    static var description = IntentDescription("Add a new item to your list")
    
    @Parameter(title: "Item Name")
    var itemName: String
    
    func perform() async throws -> some IntentResult & ProvidesDialog {
        // Add item to your app's data store
        await DataManager.shared.addItem(named: itemName)
        
        return .result(
            dialog: "Added \(itemName) to your list"
        )
    }
}

// Register in your App struct
@main
struct MyApp: App {
    var body: some Scene {
        WindowGroup {
            ContentView()
        }
    }
    
    init() {
        // Register app intents
        AppDependencyManager.shared.add(dependency: DataManager.shared)
    }
}

🎯 Best Practices for 2025

1. Embrace Concurrency

// Use structured concurrency
func loadUserData() async throws -> UserData {
    async let profile = loadProfile()
    async let preferences = loadPreferences()
    async let history = loadHistory()
    
    return try await UserData(
        profile: profile,
        preferences: preferences,
        history: history
    )
}

2. Leverage SwiftData

import SwiftData

@Model
class Task {
    var title: String
    var isCompleted: Bool
    var createdAt: Date
    
    init(title: String) {
        self.title = title
        self.isCompleted = false
        self.createdAt = Date()
    }
}

// In your App
@main
struct TaskApp: App {
    var body: some Scene {
        WindowGroup {
            ContentView()
        }
        .modelContainer(for: Task.self)
    }
}

3. Optimize Performance

// Use lazy loading for large datasets
struct LazyItemList: View {
    @State private var items: [Item] = []
    
    var body: some View {
        LazyVStack {
            ForEach(items) { item in
                ItemRow(item: item)
                    .onAppear {
                        if item == items.last {
                            loadMoreItems()
                        }
                    }
            }
        }
    }
    
    private func loadMoreItems() {
        // Load more items asynchronously
        Task {
            let newItems = await ItemService.loadMore()
            items.append(contentsOf: newItems)
        }
    }
}
