Issue Details

On iOS and MacCatalyst, the CollectionView.Scrolled event reports an incorrect FirstVisibleItemIndex after a programmatic ScrollTo() call. The reported index does not match the actual first visible item displayed on the screen.

Root Cause

The previous implementation used IndexPathsForVisibleItems.First() to determine the first visible item. On iOS/MacCatalyst, that collection can include prefetched cells outside the actual viewport, so the reported first visible index could be earlier than the item shown at the leading edge.

Description of Change

Updated the iOS CollectionView delegators to compute the first visible item from LayoutAttributesForElementsInRect(...) and select the first visible cell that intersects the current viewport. This avoids relying on prefetched cells when raising Scrolled.

Applied the fix to both:

ItemsViewDelegator.cs
ItemsViewDelegator2.cs

Validated the behavior in the following platforms

Android
Windows
iOS
Mac

Pull request overview

This PR fixes an issue where CollectionView.Scrolled event reports incorrect FirstVisibleItemIndex values on iOS and MacCatalyst after a programmatic ScrollTo() call. The root cause was that the previous implementation relied on IndexPathsForVisibleItems.First(), which includes prefetched cells that are not actually visible on screen.

Changes:

Replaced the direct use of IndexPathsForVisibleItems.First() with a new GetIndexPathAtPoint() method that uses IndexPathForItemAtPoint() to determine the actual first visible item
Applied the same logic for determining the center item index
Added UI tests to verify the fix works correctly

+        Assert.That(firstIndexText, Is.EqualTo("FirstVisibleItemIndex: 15"));


The test may have a timing issue. After tapping the button, the test immediately reads the label text without waiting for the scroll animation to complete or for the label to update. This could lead to a race condition where the test reads the old value before the Scrolled event fires and updates the label.

Consider adding a wait or retry mechanism to ensure the label has been updated with the expected value. For example, you could use App.WaitForElement with a lambda that checks for the expected text, or add Task.Delay similar to other tests that wait for scroll animations (see Issue18961.cs line 29 which uses await Task.Delay(1000) after a scroll).

The PlatformAffected attribute should include macOS (MacCatalyst). According to the linked issue #33614, this bug affects both iOS and MacCatalyst. Since MacCatalyst uses the same iOS handlers (Items2/iOS), the fix applies to both platforms. The attribute should be updated to PlatformAffected.iOS | PlatformAffected.macOS.

🔧 Try-Fix Continuation (Attempts 5-6)

Previous comment hit GitHub's 65536 character limit. Continuing with remaining attempts...

Fix Attempt 5: Leading-edge Proximity with AdjustedContentInset

Model: gpt-5.1-codex-max
Status: ✅ PASS

Approach: Uses AdjustedContentInset (modern iOS API that accounts for safe area) combined with proximity calculation to find the first truly visible item.

// Calculate visible area top edge using AdjustedContentInset
var visibleTop = collectionView.ContentOffset.Y + collectionView.AdjustedContentInset.Top;

// Find first item whose top edge is at or below visible area
foreach (var indexPath in indexPathsForVisibleItems)
{
    var attrs = collectionView.CollectionViewLayout.LayoutAttributesForItem(indexPath);
    if (attrs != null && attrs.Frame.Y >= visibleTop - 1) // 1pt tolerance
        return indexPath;
}

Key Advantages:

✅ Uses AdjustedContentInset for accurate safe area handling
✅ Proximity tolerance handles sub-pixel positioning
✅ Works with modern iOS layout patterns

Fix Attempt 6: Binary Search + Layout Attributes

Model: claude-sonnet-4
Status: ✅ PASS

Approach: O(log n) binary search through IndexPathsForVisibleItems, querying layout system for each candidate.

static NSIndexPath GetFirstTrulyVisibleIndexPath(UICollectionView collectionView, List<NSIndexPath> items)
{
    var visibleTop = collectionView.ContentOffset.Y + collectionView.ContentInset.Top;
    int lo = 0, hi = items.Count - 1;
    NSIndexPath result = items[0];
    
    while (lo <= hi)
    {
        int mid = (lo + hi) / 2;
        var attrs = collectionView.CollectionViewLayout.LayoutAttributesForItem(items[mid]);
        if (attrs != null && attrs.Frame.Y >= visibleTop)
        {
            result = items[mid];
            hi = mid - 1; // Look for earlier item
        }
        else
        {
            lo = mid + 1;
        }
    }
    return result;
}

Key Advantages:

✅ O(log n) complexity vs O(n) for iteration
✅ Uses layout system as authority
✅ Efficient for large collections

🏆 Model Consensus: Best Approach

Three models (opus, gpt-5.2-codex, gemini) evaluated all 7 approaches:

Approach	Opus Rank	GPT-5.2 Rank	Gemini Rank	Average
LayoutAttributesForElementsInRect	3rd	🥇 1st	🥇 1st	1.67 ⭐
AdjustedContentInset	🥇 1st	5th	4th	3.33
IndexPath + LayoutAttributes	7th	🥈 2nd	🥈 2nd	3.67
VisibleCells Intersection	5th	🥉 3rd	🥉 3rd	3.67
Multi-point probe	4th	4th	5th	4.33
PR Fix (Original)	🥈 2nd	6th	6th	4.67
Binary search	6th	7th	7th	6.67

Recommendation

The current PR fix is acceptable for this issue:

✅ Solves the reported bug
✅ Verified: FAIL without fix → PASS with fix
✅ Simple O(1) implementation

For future robustness (grid layouts, gaps, headers), LayoutAttributesForElementsInRect would be more comprehensive.

Issue: #33614 - [iOS, Mac] CollectionView Scrolled event reports incorrect FirstVisibleItemIndex after programmatic ScrollTo
PR: #33719 - [iOS] Fix incorrect FirstVisibleItemIndex reported by CollectionView.Scrolled after programmatic scroll
Platforms Affected: iOS, MacCatalyst
Files Changed: 2 implementation, 2 test

Key Findings

The linked issue reports the bug on both iOS and MacCatalyst after ScrollTo(index, position: ScrollToPosition.Start, animate: true), with incorrect FirstVisibleItemIndex even after scrolling completes.
The PR updates both iOS handler implementations (Items/ and Items2/) to derive the first visible item from LayoutAttributesForElementsInRect, explicitly filtering to visible cells rather than trusting prefetched IndexPathsForVisibleItems ordering.
Added coverage is a UI test pair for issue 33614 (TestCases.HostApp + TestCases.Shared.Tests), so Gate should use the UI verification path on iOS.
Existing review feedback identified two remaining risks to validate: the UI test may be timing-sensitive after animated scrolling, and the HostApp issue page still declares only PlatformAffected.iOS even though the issue and handler change affect MacCatalyst too.
Prior review history exists on the PR, including a human request to evaluate LayoutAttributesForElementsInRect; the current patch appears to incorporate that direction, but the branch labels show the previous agent run was incomplete.

Edge Cases / Discussion Notes

The issue is validated on MAUI 9.x and 10.x and specifically calls out both iOS and Mac platform reproduction.
Because this uses animated programmatic scroll, correctness depends on final visible geometry rather than prefetched cell membership.
If the new UI test reads the label before the scroll animation finishes, Gate may expose a race rather than a handler bug.

Summary

PR #33719 fixes the reported iOS and MacCatalyst CollectionView bug by replacing the naive use of IndexPathsForVisibleItems.First() with a visible-rect layout-attribute query. The gate verified that the added UI test actually catches the bug on iOS. Independent try-fix exploration found several other geometry-based solutions that also pass, but the PR's approach is the most robust of the passing options.

Root Cause

UIKit can include prefetched cells in IndexPathsForVisibleItems even when those cells are already outside the viewport after a programmatic ScrollTo animation. Using the first entry from that collection therefore reports a stale first visible item index. Any correct fix must derive the answer from the collection view's current visible geometry at the time the Scrolled event is raised.

Fix Quality

The PR fix directly interrogates the visible rect through LayoutAttributesForElementsInRect, filters to actual cells, and chooses the earliest visible item. Compared with the passing alternatives, it has the best tradeoff of correctness and robustness because it does not depend on visible-index ordering, hit-test probe fallbacks, or cell lifecycle timing. The extra stateful cross-pollination idea failed exactly because lifecycle bookkeeping lags the final Scrolled callback, which reinforces that the PR's geometry-at-query-time approach is the right class of solution.

Residual Notes

The added UI test passed in gate verification, although it still reads the label immediately after tapping the animated ScrollTo trigger; that is worth keeping an eye on if future flakiness appears.
The HostApp issue page still declares PlatformAffected.iOS even though the issue description and handler fix cover MacCatalyst too; this does not block approval for the iOS review requested here, but it is a follow-up worth considering.

📋 Expand PR Finalization Review

PR #33719 Finalization Review

Title

Current: [iOS] Fix incorrect FirstVisibleItemIndex reported by CollectionView.Scrolled after programmatic scroll

Assessment: Good as-is.

It is specific, searchable, and matches the implementation at a high level.

Description

Assessment: Needs update before merge.

The current body is no longer accurate:

It says the fix added a GetIndexPathAtPoint() method, but the actual implementation uses GetFirstVisibleIndexPathUsingLayoutAttributes(...) with LayoutAttributesForElementsInRect(...).
It says Android and Windows were validated, but the code changes are iOS/MacCatalyst-only and the PR does not include evidence for Android/Windows validation.
The issue and test coverage target both iOS and MacCatalyst, but the write-up does not clearly reflect the final platform scope.

Recommended direction: Keep the existing NOTE block and issue context, but update the Description of Change to describe the final layout-attributes-based approach and narrow the validation/platform wording to what was actually exercised.

A good replacement for the main body would be:

### Issue Details
On iOS and MacCatalyst, `CollectionView.Scrolled` could report an incorrect `FirstVisibleItemIndex` after a programmatic `ScrollTo(..., position: ScrollToPosition.Start, animate: true)`.

### Root Cause
The previous implementation used `IndexPathsForVisibleItems.First()` to determine the first visible item. On iOS/MacCatalyst, that collection can include prefetched cells outside the actual viewport, so the reported first visible index could be earlier than the item shown at the leading edge.

### Description of Change
Updated the iOS CollectionView delegators to compute the first visible item from `LayoutAttributesForElementsInRect(...)` and select the first visible cell that intersects the current viewport. This avoids relying on prefetched cells when raising `Scrolled`.

Applied the fix to both:
- `src/Controls/src/Core/Handlers/Items/iOS/ItemsViewDelegator.cs`
- `src/Controls/src/Core/Handlers/Items2/iOS/ItemsViewDelegator2.cs`

Added a HostApp repro page and UITest for issue #33614.

### Issues Fixed
Fixes #33614

Code Review Findings

Critical issues

1. UITest is race-prone after animated ScrollTo

File: src/Controls/tests/TestCases.Shared.Tests/Tests/Issues/Issue33614.cs
Problem: The test taps ScrollToButton and immediately reads FirstIndexLabel. Because the scroll is animated (animate: true), the label can still contain the old value when the assertion runs.
Why it matters: This can produce intermittent failures even if the handler fix is correct.
Recommendation: Wait for the expected post-scroll state before asserting, similar to other scrolling tests in this repo. For example, wait/retry until FirstIndexLabel becomes FirstVisibleItemIndex: 15, or use a deliberate async delay pattern if no better wait primitive is available.

2. Issue page metadata should include MacCatalyst

File: src/Controls/tests/TestCases.HostApp/Issues/Issue33614.cs
Problem: The page is marked with PlatformAffected.iOS, but issue [iOS, Mac] CollectionView Scrolled event reports incorrect FirstVisibleItemIndex after programmatic ScrollTo #33614 is explicitly filed for both iOS and macOS, and this PR updates both shared iOS handlers (Items/ and Items2/) used by MacCatalyst.
Why it matters: The test metadata understates the affected platform surface and makes the issue page harder to discover/run for MacCatalyst verification.
Recommendation: Update the attribute to include macOS/MacCatalyst, e.g. PlatformAffected.iOS | PlatformAffected.macOS.

Suggestions

Consider updating the PR description to mention that the final implementation followed the review feedback favoring LayoutAttributesForElementsInRect(...).
If the author wants to keep the platform prefix broad, the current title is acceptable; the more important fix is making the body accurate.

Looks good

The functional fix was applied to both iOS handler stacks: legacy Items/ and current Items2/, which keeps behavior aligned.
Using layout attributes to determine the first visible item is a better match for the reported prefetching problem than relying on IndexPathsForVisibleItems.First().
The PR includes a targeted HostApp repro page plus a UITest, which is the right validation shape for this bug.

Merge readiness

Recommendation: Not ready to merge yet.

The handler change itself looks reasonable, but I would address the two open review items above and refresh the PR description before merging.

Additional note: GitHub check metadata for this PR is not currently green from the data I could read (maui-pr shows failures and one run still appears in progress/pending). I did not investigate CI failures here because that is outside this skill's scope.
