April 2026 - Maui delivered cross-platform UX and reliability improvements. Key feature: extend Keep Screen On to Mac Catalyst using IOKit assertions to prevent unwanted sleep, aligning with iOS behavior while respecting Mac semantics. Major fixes: Android HideSoftInputOnTapped regression on modals now dismisses the keyboard by forwarding touch events to the MAUI window; SwipeView tap reliability improved by refining touch interception logic. Impact: improved user experience and stability across Mac, Android, and iOS; increased test coverage with automated UI tests. Skills demonstrated: Mac Catalyst interop with IOKit (P/Invoke), Android touch event routing, MAUI Modal Navigation enhancements, and test automation for regression safety.
