Issue details

After a swipe, the carousel could move visually, but it did not consistently snap to a single item or reliably update the Position.

Root cause

The vertical CarouselView path in LayoutFactory2.cs had inconsistent behavior:

Vertical CarouselView was not routed through the custom snap-enabled compositional layout
Page tracking still used horizontal offset/width calculations
Loop correction still relied on a horizontal scroll anchor

Because these were not aligned to the vertical axis, the control could move visually while leaving Position updates stale or inconsistent.

Description of change

This PR updates the iOS CarouselView layout path in LayoutFactory2.cs to handle the vertical flow consistently end to end:

Route vertical linear CarouselView through CustomUICollectionViewCompositionalLayout
Compute page progression using the vertical axis (offset.Y and container height)
Use UICollectionViewScrollPosition.Top for vertical loop correction

With these changes, snapping, page calculation, loop repositioning, and Position updates all follow a consistent vertical model.

Issues Fixed

Fixes #33308

Technical Details

The fix is implemented in src/Controls/src/Core/Handlers/Items2/iOS/LayoutFactory2.cs.

CreateCarouselLayout(...) now detects vertical LinearItemsLayout and routes it through CustomUICollectionViewCompositionalLayout.
VisibleItemsInvalidationHandler calculates page progression using vertical offset and container height for vertical carousels.
Vertical loop correction uses UICollectionViewScrollPosition.Top instead of a horizontal anchor.

This ensures that layout selection, snap behavior, page calculation, and final Position updates are all aligned along the same vertical axis.

Issue: #33308 - CarouselView vertical snap points ignored on iOS with Microsoft.Maui.Controls v10.0.20 (regression from v9.0.120)
PR: #34700 - [iOS] Fix vertical CarouselView MandatorySingle snapping on iOS
Platforms Affected: iOS (fix is iOS-specific via Items2/iOS handler)
Files Changed: 1 implementation (LayoutFactory2.cs), 2 test files, 3 snapshot files

Key Findings

Regression: Vertical CarouselView with SnapPointsType=MandatorySingle stopped snapping on iOS in the CV2 (Items2) handler introduced in .NET 10. The .NET 9 handler still works as a workaround.
Root cause: CreateCarouselLayout() in LayoutFactory2.cs always created a plain UICollectionViewCompositionalLayout (no snap override) even for vertical carousels with snap points. Only the horizontal path was effectively snapped via CustomUICollectionViewCompositionalLayout's TargetContentOffset override.
Three related bugs fixed together:
1. Vertical snap: Not routed through CustomUICollectionViewCompositionalLayout
2. Page tracking: Used offset.X / width (horizontal) even for vertical carousels
3. Loop correction: Used UICollectionViewScrollPosition.Left instead of .Top for vertical
Previous agent review found a constructor arity bug. That has since been fixed — the PR now correctly passes 6 arguments to CustomUICollectionViewCompositionalLayout.
Copilot suggestions addressed: snap-only routing (SnapPointsType != None), carouselView rename, App.WaitForElement("Card 2") added, cross-platform test justified.
Test coverage: HostApp page sets AutomationId="CardsCarousel" on the carousel. Shared test scrolls down and waits for "Card 2" then verifies screenshot. Snapshots added for ios, ios-26, and android.

Selected Fix: PR's fix — it uses the existing proven CustomUICollectionViewCompositionalLayout/SnapHelpers pipeline which correctly handles all SnapPointsType values, all SnapPointsAlignment values, and peek area insets.

Summary

PR #34700 fixes a regression in the iOS CV2 (Items2) handler where vertical CarouselView with SnapPointsType=MandatorySingle scrolled freely instead of snapping. The fix correctly routes vertical+snap carousels through the existing CustomUICollectionViewCompositionalLayout snap infrastructure and fixes three axis-alignment bugs. The Gate confirmed the fix works. Three independent alternative approaches also passed, and cross-pollination confirmed the PR's approach is the most robust of the candidates.

Root Cause

CreateCarouselLayout() in LayoutFactory2.cs always created a plain UICollectionViewCompositionalLayout for all carousels — including vertical ones with snap points — giving it no TargetContentOffset override. Additionally, the VisibleItemsInvalidationHandler computed page position using offset.X / containerWidth (horizontal math) regardless of orientation, and the loop correction always used UICollectionViewScrollPosition.Left, causing stale Position updates for vertical carousels.

Fix Quality

The PR's fix is well-structured and appropriately scoped:

Strengths:

Routes vertical+snap carousels through CustomUICollectionViewCompositionalLayout, reusing the proven SnapHelpers pipeline that already handles all SnapPointsType values, all SnapPointsAlignment values (Start/Center/End), and peek area insets. This is the architecturally correct approach — mirrors exactly how horizontal carousels work.
Fixes all three axis bugs consistently: Y-offset for page calc, VerticalThickness for section margin, .Top for loop correction.
Guards on SnapPointsType != None so non-snap vertical carousels are unaffected (no behavior regression risk).
Previous Copilot feedback fully addressed: carouselView rename, snap-only routing condition, App.WaitForElement("Card 2") assertion added.
Constructor call is now correct (6 args: LayoutSnapInfo, null grouping, null headerFooter, sectionProvider, layoutConfiguration, ItemsUpdatingScrollMode).

Minor notes (non-blocking):

layoutConfiguration.ScrollDirection is not explicitly set for the vertical path, relying on the default UICollectionViewScrollDirection.Vertical. This is correct but an implicit dependency. A one-line layoutConfiguration.ScrollDirection = UICollectionViewScrollDirection.Vertical (or a comment) would make the intent explicit, though this is cosmetic.
The test uses #if TEST_FAILS_ON_WINDOWS which correctly excludes only Windows; Android and MacCatalyst snapshots are included appropriately given the test runs cross-platform.

Why PR's fix beats alternatives:

Attempts 1/2 ("flip primary to horizontal"): Achieves paging via GroupPagingCentered orthogonal behavior, which only supports full-group paging. It does not handle non-MandatorySingle snap types, arbitrary SnapPointsAlignment, or peek area insets correctly for all configurations.
Attempt 3 (minimal subclass with round(offset.Y / pageHeight)): Works for center-aligned full-page carousels but misses SnapPointsAlignment (Start/End targets) and peek area insets, which SnapHelpers handles.
Attempt 4 (section OrthogonalScrollingBehavior only): Failed — UIKit does not apply section-level paging for primary-axis vertical scroll.
