Elliot Windsor enhanced the gronxb/hot-updater repository by improving the iOS HotUpdater’s responsiveness and stability during in-app updates. He implemented an asynchronous updateBundle method with a completion callback, ensuring the UI thread remained unblocked and responsive throughout the update process. To further optimize performance, he introduced throttling of progress events, reducing React Native update frequency and minimizing UI disruptions. Working primarily with Objective-C and leveraging asynchronous programming techniques, Elliot addressed UI thread blocking issues in update event emissions. His focused contributions delivered a smoother user experience and lower update latency, demonstrating depth in iOS development and React Native integration.
