Summary
Views/TodoListPage.xaml's ListView sets IsSwipeEnabled="True", but Uno Platform doesn't implement this property outside of WinUI/Windows:
warning Uno0001: Microsoft.UI.Xaml.Controls.ListViewBase.IsSwipeEnabled is not implemented in Uno (https://aka.platform.uno/notimplemented?m=Microsoft.UI.Xaml.Controls.ListViewBase.IsSwipeEnabled) (https://aka.platform.uno/notimplemented)
CI run: https://github.com/CommunityToolkit/Datasync/actions/runs/29093946725 (android, browserwasm, desktop, ios-maccatalyst todoapp-uno jobs - not windows)
This is pre-existing (present before #524/#525's fixes too, confirmed locally), just newly visible now that CI builds every head.
Root cause
This is a known Uno Platform limitation, not a defect in the sample: ListViewBase.IsSwipeEnabled (and the corresponding swipe-to-reveal-actions gesture) is only implemented on the native WinUI/Windows renderer, not on any Skia-based head (android, ios, maccatalyst, browserwasm, desktop). Setting the attribute is effectively a no-op (and a compile-time warning) on every non-Windows head - no swipe gesture is available for users on those platforms.
Suggested fix / options
- Remove
IsSwipeEnabled="True" from the ListView in Views/TodoListPage.xaml.cs if swipe-to-delete isn't actually relied upon elsewhere, to eliminate dead configuration and the warning.
- Or keep it (since it's harmless on Windows and simply ignored elsewhere) and instead suppress the specific
Uno0001 diagnostic for this one property with a documented rationale, if the team wants to preserve the Windows-only swipe behavior intentionally.
- Or replace it with an Uno-native, cross-platform swipe affordance (e.g.,
Uno.Toolkit.UI's SwipeContainer/SwipeButton, which the project already references via the Toolkit UnoFeature) if cross-platform swipe-to-delete is actually a desired feature for this sample.
Recommend (1) or (2) as the minimal fix, since this project doesn't currently document swipe-to-delete as an intentional teaching point.
