PROFILE
Tomasz Boroń
Over the past year, contributed to the software-mansion/react-native-screens repository by architecting and delivering advanced navigation and modal UI components for React Native apps. Focused on building robust, cross-platform features such as FormSheet v5 and SplitView, the work emphasized modular architecture, lifecycle management, and seamless integration between JavaScript and native layers. Leveraging technologies like Swift, Kotlin, and TypeScript, implemented dynamic sizing, event-driven UX, and platform-specific optimizations for iOS and Android. Addressed complex edge cases in modal dismissal, memory management, and animation coordination, while maintaining code quality through refactoring, CI tooling upgrades, and comprehensive testing to ensure reliable, scalable releases.

May 1, 2026May 2026 performance summary for software-mansion/react-native-screens Highlights focus on FormSheet v5 capabilities, stability improvements, and CI tooling enhancements. The month delivered a production-ready evolution of the iOS FormSheet with a robust, testable architecture, along with targeted bug fixes and CI reliability improvements that reduce friction for future releases. Key features delivered: - FormSheet v5 standalone component: basic setup with iOS architecture. Introduced initial detents and a scalable 3-tier architecture for host, content, and controller. - New UI props for FormSheet v5: preferredCornerRadius, prefersGrabberVisible, largestUndimmedDetentIndex, initialDetentIndex, and prefersScrollingExpandsWhenScrolledToEdge, enabling richer, customizable sheet experiences across iOS 15, iOS 18, and iOS 26. - onDetentChanged event: added callback to observe detent transitions for UX tuning and analytics. - Presentation and appearance refactors: moved presentation logic from HostView to ContentController; introduced AppearanceCoordinator/Applicator; separate Behavior and Appearance concerns for easier maintenance and future refactors. - New PresentationManager; state-machine based handling to synchronize rapid isOpen prop changes with UIKit animations, reducing desync scenarios. - API and stability improvements: rename protocol to RNSFormSheetContentControllerDelegate; updated codegen specs; added dedicated SFTs for FormSheet scenarios. Major bugs fixed: - Android: Dismiss FormSheet only on ACTION_UP to prevent double-back navigation. - SplitView: Fix crash when maxWidth is undefined for a column, improving stability in multi-column layouts. - FormSheet with disabled gamma: Fix missing symbols to restore build stability under gamma off. - SAV wrapping regression: Examples now wrap only the selection screen, avoiding unintended wrapping of all examples. Overall impact and accomplishments: - Significantly improved reliability, configurability, and test coverage for the FormSheet component, enabling richer UIs while preserving stability across iOS versions and Android. - Reduced risk of state desynchronization between React and native sheets during rapid updates; improved testing with dedicated FormSheet SFTs and playground scenarios. - Prepared groundwork for future enhancements with a cleaner separation of concerns, paving the way for easier maintenance and faster iteration cycles. Technologies/skills demonstrated: - iOS UIKit integration and detents management (UISheetPresentationController), bridging React Native with native sheets - Architecture: ContentController, PresentationManager, AppearanceCoordinator/Applicator, UpdateCoordinator patterns - Codegen, TypeScript/JS to native bindings, and SFT-driven testing - CI tooling: clang-format 22, TVOS gamma enablement, dependency maintenance (react-navigation 7.x) Top 3-5 achievements: 1) FormSheet v5 delivered with standalone component and extensive detent/UI customization options. 2) Refactor and separation of concerns improved maintainability and reliability of the sheet lifecycle. 3) Key bug fixes (Android dismiss gating, SplitView stability, gamma build fixes) reducing churn and crash risk. 4) CI tooling upgrades and dependencies maintenance to improve developer experience and build reliability. 5) Comprehensive testing with SFTs, ensuring consistent behavior across iOS versions and scenarios.
