Score: 7.3/10 (Innovation: 7, Technical: 8, Documentation: 8, Utility: 6)

Swarm is a Swift framework for building AI agents and multi-agent workflows, combining type-safe tool macros, durable checkpointing, and support for both cloud and on-device models. It's interesting because it brings LangGraph-like DAG execution to Swift with compile-time safety and native iOS/macOS integration.

Target audience: backend devs, ios developers, ai engineers
