iOS & Swift

Apple Foundation Models

Apple Foundation Models is a practical guide to building intelligent, on-device AI applications using Apple’s new Foundation Models framework. Designed for Swift developers, this book introduces the fundamentals of large language models before guiding you through real-world implementations using Apple’s on-device AI technologies.

Throughout the book, you’ll learn how to integrate with SwiftUI interfaces, manage model sessions and context windows, engineer effective prompts, and safely work with AI-generated content. You’ll explore advanced capabilities such as Guided Generation, dynamic schemas, and integrating external tools and data sources to extend model functionality beyond static training data.

By the end of the book, you’ll bring these concepts together in complete applications that capture audio, convert speech to text, summarize information, and intelligently organize content using on-device machine learning and Foundation Models. Whether you’re exploring Apple Intelligence for the first time or looking to integrate AI into production SwiftUI apps, this book provides the practical knowledge and hands-on experience needed to confidently build modern intelligent applications.

macOS Apprentice

macOS Apprentice is a series of multi-chapter tutorials where you’ll learn about developing native macOS apps in Swift, using both SwiftUI — Apple’s newest user interface technology — and AppKit — the venerable UI framework. Along the way, you’ll learn several ways to execute Swift code and you’ll build two fully featured apps from scratch.

If you’re new to macOS and Swift, or to programming in general, learning how to write an app can seem incredibly overwhelming.

That’s why you need a guide that:

Shows you how to write an app step-by-step. Uses tons of illustrations and screenshots to make everything clear. Guides you in a fun and easy-going manner.

You’ll start at the very beginning. The first section assumes you have little to no knowledge of programming in Swift. It walks you through installing Xcode and then teaches you the basics of the Swift programming language. Along the way, you’ll explore several different ways to run Swift code, taking advantage of the fact that you’re developing natively on macOS.

macOS Apprentice doesn’t cover every single feature of macOS; it focuses on the absolutely essential ones. Instead of just covering a list of features, macOS Apprentice does something much more important: It explains how all the building blocks fit together and what is involved in building real apps. You’re not going to create quick example programs that demonstrate how to accomplish a single feature. Instead, you’ll develop complete, fully-formed apps, while exploring many of the complexities and joys of programming macOS.

This book, macOS Apprentice, is designed to teach new developers how to build macOS apps while assuming they have little to no experience with Swift or any other part of the Apple development ecosystem.

Swift Internals

This book is designed for Swift developers who want to go beyond writing working code and understand how the language truly works under the hood.

It explains the mechanics of Swift’s type system, compiler behavior, memory model, and performance characteristics. Readers will also learn advanced topics like unsafe memory operations, metaprogramming, modular architecture, and linking strategies.

The goal is to help developers reason about Swift at the language, compiler, and system levels. It is ideal for Swift engineers who want to write faster, safer, and more scalable apps.
