-- RIBs iOS now lives at [uber/RIBs-iOS](https://github.com/uber/RIBs-iOS) (not `uber/RIBs`).
-- Minimum iOS is **15** for SPM / current sources; older XCFrameworks may still show iOS 13 in metadata until regenerated.
+- RIBs for iOS: [uber/RIBs-iOS](https://github.com/uber/RIBs-iOS) (the monorepo `uber/RIBs` is Android-focused).
