IOS

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:

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
