MLX Swift & Local LLMs. Deep dive into Apple's MLX framework for high-performance machine learning.

Building custom inference engines, fine-tuning local models (LoRA), and leveraging Unified Memory directly from Swift.

Transform your Apple devices into AI powerhouses with native MLX Swift and local LLMs. Master "Metal-to-Model" workflows, leveraging unified memory for lightning-fast, zero-copy inference. Implement LoRA fine-tuning, 4-bit quantization, and real-time streaming for a superior user experience. Build the next generation of privacy-centric, offline-first AI applications directly in Swift 6.

About the Book

Unlock the full power of Apple Silicon with the definitive guide to MLX Swift and Local LLMs.

The future of Artificial Intelligence is local. In Volume 6 of the Swift & AI Masterclass, author Edgar Milvus takes you deep into the architecture of Apple's MLX framework, a high-performance array library designed for the "Metal-to-Model" experience. This isn't just about calling APIs; it's about building custom inference engines and fine-tuning models directly on your Mac, iPhone, and iPad.

What’s inside this volume:

  • Unified Memory Mastery: Learn to exploit zero-copy data sharing between CPU and GPU for lightning-fast tensor operations.
  • Local LLM Deployment: Step-by-step guides on porting HuggingFace weights and running models like Llama and Mistral natively in Swift.
  • Parameter-Efficient Fine-Tuning (LoRA): Teach your models new tricks using user-specific data without the cost of full retraining.
  • Quantization & Performance: Master 4-bit and 8-bit quantization to run multi-billion parameter models on mobile devices.
  • Streaming & Agentic Loops: Build responsive SwiftUI chat interfaces and autonomous agents that can call Swift functions as tools.

Bridging the gap between Python-based research and Swift-based production, this book provides the theoretical foundations and the production-ready code needed to build the next generation of privacy-centric, offline-first AI applications. Whether you are an experienced iOS developer or a Machine Learning engineer, this masterclass is your roadmap to AI excellence on Apple platforms.

Note: This book requires a Mac with Apple Silicon for the code examples.

About the Author

Edgar Milvus

A veteran software engineer with 20 years of experience, I have dedicated my career to the art of automation. My philosophy is simple: programming should eliminate repetitive chores to unlock human creativity. This journey began early on with the development of custom code-generation tools and has evolved into a deep mastery of LLMs and their APIs. Today, I specialize in architecting AI-driven solutions that handle everything from complex coding and security tasks to advanced knowledge retrieval, transforming the way we interact with technology

The Leanpub 60 Day 100% Happiness Guarantee

Within 60 days of purchase you can get a 100% refund on any Leanpub purchase, in two clicks.

Now, this is technically risky for us, since you'll have the book or course files either way. But we're so confident in our products and services, and in our authors and readers, that we're happy to offer a full money back guarantee for everything we sell.

You can only find out how good something is by trying it, and because of our 100% money back guarantee there's literally no risk to do so!

Earn $8 on a $10 Purchase, and $16 on a $20 Purchase

We pay 80% royalties on purchases of $7.99 or more, and 80% royalties minus a 50 cent flat fee on purchases between $0.99 and $7.98. You earn $8 on a $10 sale, and $16 on a $20 sale. So, if we sell 5000 non-refunded copies of your book for $20, you'll earn $80,000.

(Yes, some authors have already earned much more than that on Leanpub.)

In fact, authors have earned over $15 million writing, publishing and selling on Leanpub.
