About the Book
Unlock the Power of Persistent AI Memory on Apple Platforms!
In the age of Generative AI, an application is only as smart as what it can remember. Volume 9 of the Swift & AI Masterclass series is the definitive guide to building a "Second Brain" for your apps, focusing on the sophisticated integration of SwiftData, Core Data, CloudKit, and Vector Search.
This volume isn't just about storing text—it's about managing Semantic Intelligence. You will learn how to transform raw user data into high-dimensional vector embeddings and persist them in a way that is lightning-fast, thread-safe, and synchronized across the entire Apple ecosystem.
What’s inside:
- SwiftData & Swift 6: Master the new declarative persistence paradigm and use ModelActor to handle heavy AI workloads without freezing the UI.
- On-Device Vector Search: Implement hardware-accelerated Cosine Similarity and Dot Product math using the Accelerate framework.
- HNSW Graph Implementation: Build advanced Hierarchical Navigable Small World indices to search through millions of embeddings in logarithmic time.
- CloudKit Synchronization: Learn the secrets of syncing AI context and semantic memory across iPhone, iPad, and Mac using NSPersistentCloudKitContainer.
- Hybrid Search: Synthesize Full-Text Search (FTS) and Semantic Search to provide users with the most accurate results possible.
- Privacy & GDPR: Architect your data layer to respect user sovereignty, ensuring sensitive AI data is handled with "Privacy by Design."
Whether you are building a personal knowledge assistant, a smart research tool, or an AI-driven journaling app, this book provides the architectural blueprints you need to scale from a local prototype to a production-grade distributed system.
Master the art of persistent intelligence. Build apps that remember, understand, and sync.

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
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.
