Worked on the AvaloniaUI/Avalonia repository to address a critical issue with iOS cold-launch URL handling, focusing on Universal Links and custom schemes. Using C# and the Avalonia Framework, implemented a fix that preserves URL data and user activities during cold launches by draining UISceneConnectionOptions and routing URL contexts through a unified activation path. The solution included adding a scene:openURLContexts: handler and exposing OpenUrl in the internal delegate, aligning the app’s lifecycle with iOS 13+ scene-based requirements. This work resolved lifecycle reliability issues, improved user experience, and provided manual verification steps for future test fixture integration.
Monthly summary for 2026-05 for repository AvaloniaUI/Avalonia focused on stabilizing iOS cold-launch URL handling for Universal Links and custom schemes, improving lifecycle reliability and user experience. Delivered a robust fix that ensures URLs and user activities delivered during cold launches are correctly processed, enabling the app to raise ProtocolActivatedEventArgs with the URL rather than a base ActivatedEventArgs. Implemented through draining UISceneConnectionOptions in WillConnectToSession, adding a scene:openURLContexts: handler, and exposing OpenUrl in IAvaloniaAppInternalDelegate to route URL contexts through the existing activation paths. This work closes issues around cold-launch URL loss and aligns with iOS scene-based lifecycle (iOS 13+).
