iOS 18 Programming for Beginners with Swift 6

Learn iOS 18 app development from scratch and publish your first iPhone app to the App Store using Swift 6, Xcode 16, and SwiftUI

Key Features

Build 6 complete iOS applications from a weather app to a publishable expense tracker Master modern SwiftUI declarative UI development without learning outdated UIKit patterns Learn async/await networking, SwiftData persistence, and state management through hands-on projects Understand the complete app development lifecycle from concept to App Store submission

iOS app development has never been more accessible, yet most beginners struggle to bridge the gap between watching tutorials and building real applications. This comprehensive guide takes a project-first approach, teaching you iOS 18 development by building six complete, production-ready applications using Swift 6 and SwiftUI.

Starting with Swift fundamentals, you'll quickly progress to building user interfaces with SwiftUI's declarative syntax. Each chapter introduces new concepts through practical implementation—you'll create a profile screen to understand layouts, build a settings app to master navigation and forms, and develop a to-do list to grasp state management. As you advance, you'll fetch real-time data by building a weather app with networking and JSON parsing, implement local data persistence through a notes application using SwiftData, and combine everything into a complete expense tracker ready for App Store publication.

The book emphasizes modern iOS development practices, focusing exclusively on SwiftUI rather than legacy UIKit approaches. You'll work with Swift 6's latest features including structured concurrency with async/await, the Observable macro for state management, and SwiftData for persistence. Throughout the journey, you'll learn professional development skills including debugging with breakpoints, writing tests, handling errors gracefully, and preparing your app for submission.

By the end of this book, you'll have published your first app to the App Store and gained the confidence to build any iOS application you can imagine.

What you will learn

Write Swift 6 code with proper syntax, functions, and data structures Build responsive user interfaces using SwiftUI's declarative components Manage application state with State, Binding, and Observable patterns Fetch and parse data from web APIs using URLSession and Codable Store data locally on device using SwiftData persistence framework Navigate between screens with NavigationStack and pass data effectively Debug applications using print statements, breakpoints, and Xcode tools Test your code with Swift Testing framework for reliable applications Submit your completed app to the App Store following Apple's guidelines

Who this book is for

This book is for absolute beginners with no prior programming experience who want to build iOS apps, web developers looking to transition to native iOS development, entrepreneurs who need to prototype their app ideas, and anyone who has started learning iOS but struggled to complete a real project. You'll need a Mac computer running macOS Sonoma or later and willingness to type code and debug errors. No Swift or programming knowledge is assumed.
