Issue #124 of Fatbobman's Swift Weekly opens with a commentary on humanoid robotics showcased at China's Spring Festival Gala, clarifying misconceptions about pre-trained motion control vs. LLMs, and reflecting on the future of Embodied AI. The curated links cover: migrating from ObservableObject to @Observable in SwiftUI, testing sequential async callbacks with AsyncStream in Swift Testing, SwiftData schema versioning best practices, building CLI tools with Swift's ArgumentParser, agentic coding workflows and CI/CD pipeline design for iOS, token usage tracking in Apple's on-device Foundation Models, and notable tool releases including GRDB 7.10.0 (now supporting Android/Linux/Windows) and Swift System Metrics 1.0.
