Swift Use this skill for Swift code that needs strong API boundaries, predictable threading, and idiomatic Apple-platform integration. When the code is part of a Nitro Module, pair this with for generated specs, Promise mapping, and HybridObject constraints. Workflow 1. Read the local Swift code, generated protocols, and surrounding API shape before editing. 2. Choose the public type model first: make invalid states unrepresentable where Swift can express them. 3. Choose one concurrency model for the feature before writing implementation code. 4. Keep synchronous properties and methods cheap,…
