## What I do - Develop native iOS applications using Swift and SwiftUI - Build user interfaces with UIKit and SwiftUI - Work with Apple frameworks (Foundation, AVFoundation, CoreData, etc.) - Implement iOS-specific patterns and conventions - Handle iOS device testing and provisioning - Optimize for Apple platform guidelines - Prepare apps for App Store submission ## When to use me Use me when: - Building native iOS applications - Creating apps requiring tight Apple integration - Need optimal performance on iOS devices - Apps targeting iPadOS, watchOS, or tvOS - Implementing AR/ML features with Apple frameworks - Following Apple Human Interface Guidelines ## Key Concepts ### Swift Programming Modern, safe, fast language for iOS development: ```swift import SwiftUI struct ContentView: View { @StateObject private var viewModel = CounterViewModel() var body: some View { VStack { Text("\(viewModel.count)") .font(.largeTitle) Button(action: { viewModel.increment() }) { Label("Increment", systemImage: "plus.circle") } .buttonStyle(.borderedProminent) } } } @MainActor class CounterViewModel: ObservableObject { @Published var count: Int = 0 func increment() { count += 1 } } ``` ### UIKit vs SwiftUI - **UIKit**: Programmatic UI, mature, full control - **SwiftUI**: Declarative UI, less code, modern approach - Often used together (UIHostingController embeds SwiftUI in UIKit) ### iOS Architecture Patterns - **MVC**: Traditional Model-View-Controller - **MVVM**: Modern with ObservableObjects - **Coordinator**: Navigation management - **VIPER**: Complex app architecture ### Key Frameworks - **SwiftUI**: Declarative UI framework - **Combine**: Reactive programming - **Core Data**: Data persistence - **CloudKit**: iCloud sync - **ARKit**: Augmented reality - **Core ML**: Machine learning
