summary
React Native talks to Apple Watch using Apple’s WatchConnectivity SDK so a React Native app calls a bridged Objective-C native module that uses WCSession to send NSDictionary payloads and optional reply handlers. The watch app runs in Swift, implements didReceiveMessage, loads data into a native table, and can trigger React Navigation on the iPhone. Demo shows a dog list syncing quickly over Bluetooth, recommends background file transfer for images and warns about payload size limits.
