Window scope disposed first, then iOS calls TraitCollectionDidChange, but renderer's Dispose() hasn't been called yet. The ServiceProvider is disposed before the renderer knows it's disposed. | +| 2 | try-fix | Store `IApplication` in `WeakReference` | ✅ PASS | `ShellSectionRootRenderer.cs` (+13) | Claude Sonnet 4.5 | **Why works:** Captures IApplication at construction time before service provider disposed. WeakReference allows GC to collect if needed. No ObjectDisposedException because we never touch the disposed service provider. | +| 3 | try-fix | Use `Application.Current` instead of service provider | ✅ PASS | `ShellSectionRootRenderer.cs` (+12) | Claude Sonnet 4.5 | **Why works:** `Application.Current` is a static property that doesn't go through the scoped service provider. Cast to `IApplication` to call `ThemeChanged()`. Simpler than WeakReference approach. **PREFERRED - simplest solution.** | +| 4 | try-fix | Try-catch `ObjectDisposedException` | ✅ PASS | `ShellSectionRootRenderer.cs` (+14) | Claude Sonnet 4.5 | **Why works:** Catches and swallows ObjectDisposedException. Theme change not critical during disposal. Works but less elegant than avoiding the exception. | +| 5 | try-fix | Remove override entirely | ❌ N/A | - | Claude Sonnet 4.5 | **Not applicable:** Method is in PublicAPI.Shipped.txt, removing it would be breaking change. Would require API removal process. | +| 6 | try-fix | Null-check `FindMauiContext()` + try-catch | ✅ PASS | `ShellSectionRootRenderer.cs` (+19) | Claude Sonnet 4.5 | **Why works:** Double protection - null check first, then try-catch. More defensive but verbose. | +| 7 | try-fix | Check if Shell's Window is null | ❌ FAIL | `ShellSectionRootRenderer.cs` (+15) | Claude Sonnet 4.5 | **Why failed:** Window property is still set when TraitCollectionDidChange called. Window.Parent disconnection happens after TraitCollectionDidChange, so checking Window is null doesn't help. | +| 8 | try-fix | Check if Window.Handler is null | ✅ PASS | `ShellSectionRootRenderer.cs` (+16) | Claude Sonnet 4.5 | **Why works:** Window.Handler is disconnected before service provider disposed. Checking `window?.Handler == null` catches the disconnection state. Good approach for detecting window closure. | +| 9 | try-fix | Check if Shell.Parent is null | ❌ FAIL | `ShellSectionRootRenderer.cs` (+15) | Claude Sonnet 4.5 | **Why failed:** Shell.Parent (Window) still set when TraitCollectionDidChange called. Shell remains attached to Window during disposal sequence. | +| 10 | try-fix | Combine `Application.Current` with Window.Handler check | ✅ PASS | `ShellSectionRootRenderer.cs` (+21) | Claude Sonnet 4.5 | **Why works:** Best of both: Window.Handler check catches disconnection early, Application.Current avoids service provider entirely. Most defensive approach. | +| 11 | try-fix | Check `Window.IsDestroyed` (internal flag) | ✅ PASS | `ShellSectionRootRenderer.cs` (+16) | Claude Sonnet 4.5 | **Why works:** `IsDestroyed` is set to true at line 540 of Window.Destroying(), BEFORE DisposeWindowScope() at line 558.

Thank you! + +### Description of Change + +This PR fixes VoiceOver accessibility on iOS for Picker, DatePicker, and TimePicker controls. When picker popups open/close, VoiceOver now properly shifts focus using iOS accessibility notifications. + +**Root cause:** VoiceOver on iOS requires explicit focus notifications via `UIAccessibility.PostNotification(ScreenChanged, view)` when modal UI appears or dismisses. Without these notifications, VoiceOver doesn't know to shift focus, leaving users navigating background controls instead of the picker popup. + +**Fix:** +- Adds `PostAccessibilityFocusNotification()` extension methods in `SemanticExtensions.cs` +- Posts `ScreenChanged` notification when picker popups open (in `EditingDidBegin` event) +- Posts `ScreenChanged` notification to restore focus when popups close (in `EditingDidEnd` event) +- Handles edge cases: null window checks, main thread dispatch for delayed InputView availability + +**Tests:** UI tests created in `Issue30746.xaml[.cs]` and marked with `ManualReview` category since VoiceOver focus cannot be automated with Appium. Manual testing with VoiceOver enabled confirms proper focus behavior. + +### Issues Fixed + +Fixes #30746 +``` + +### Code Review Notes + +**Inline Suggestions (from Copilot):** +1. PickerHandler.iOS.cs:109 - Add space after `if` keyword ✓ Minor style +2.
