Sandboxed - On-Device AI for iOS

Vision Framework Integration: The Hello World of AI

We move from theory to practice by building a real-time image classifier from scratch. We explore the architectural challenges of integrating Core ML into an iOS app, using the Vision framework as the critical "transmission" between the camera sensor and the model engine.

Model Selection Strategy: When to Reject AI

We explore the architectural discipline of knowing when to use Machine Learning and when to stick with deterministic code. We dissect the "AI Everywhere" trap, compare the costs of Code 1.0 vs Code 2.0, and establish the "Certainty Gap".

Privacy Preserving AI: The Architecture of Trust

We explore the architectural tension between AI capability and user confidentiality. From the Secure Enclave to Private Cloud Compute, we breakdown how Apple builds trust into the silicon itself.

Apple ML Frameworks: The Abstraction Onion

Sam and Alex peel back the layers of Apple's machine learning stack. They navigate from the high-level magic of the Vision framework down through the engine room of Core ML and finally to the bare metal physics of Accelerate. The goal: teaching developers how to choose the right tool for the job to save battery, thermal headroom, and sanity.

The Compiler & The Chip: How Code Becomes Thinking

We strip away the "Interpreted AI" myth to reveal the reality of the Core ML Compiler. We explore Layer Fusion, the ANE's Systolic Array architecture, the "Ping-Pong" performance trap, and why shipping a `.mlpackage` is actually shipping a blueprint for a silicon factory.
