What problem does it solve? Integrating Meta smart glasses into an iOS app requires correct package setup, registration, permissions, URL callbacks, and session lifecycle handling against a specific DAT SDK release, and mistakes in any of these produce broken pairing flows or untestable code. ## Core Features & Use Cases - Source-checked package setup: Pins the official DAT iOS repository tag or commit and verifies the actual SPM products and modules exposed by that release before writing code. - Explicit adapter state machine: Models registration, permission, session, denial, and failure states outside of SwiftUI views so the phone app stays useful without glasses. - 0.9 migration review: Checks release-specific API changes such as DeviceSession.addCamera, stream completion, and ListenerTokenBag behavior against the official changelog. - Use Case: When adding Meta glasses camera support to an iOS app, use this Skill to configure the package, build the registration and session adapter, and plan mock-device tests before touching physical hardware. ## Quick Start Integrate the Meta Wearables Device Access Toolkit into my iOS app with registration, permissions, and a testable session lifecycle.
