A comprehensive, modern guide to building iOS applications — the apps that run on iPhone, iPad, and the broader Apple ecosystem.

Welcome to iOS Application Development: From First App to Professional.

A comprehensive, modern guide to building iOS applications — the apps that run on iPhone, iPad, and the broader Apple ecosystem. It teaches the contemporary Apple stack: Swift, declarative UI with SwiftUI, sound app architecture (MVVM with Observation), Swift Concurrency (async/await), local data with SwiftData/Core Data, networking with URLSession and Codable, dependency injection, testing, and publishing on the App Store — carrying you from your first screen to the skills of a working professional.

This title is part of the ShriIra library and is free to read in full, right here — our small contribution to making world-class knowledge easy to reach.

A note on reading it: open the Contents menu at the top of the reader to jump between chapters, use the Aa menu to set a comfortable text size, theme (light, sepia, or night), and single- or two-page layout. Your place is saved automatically, so you can always pick up where you left off.

We hope it serves you well.
