Issue Details
CollectionView’s programmatic ScrollTo does not work when using a horizontal ItemsLayout on iOS/MacCatalyst. After calling ScrollTo(index, position: ScrollToPosition.Start, animate: true), the scroll position remains unchanged.
Root Cause
In the CV2 iOS handler, the scroll direction is hardcoded to Vertical instead of using the actual layout direction. As a result, horizontal layouts receive incorrect scroll position calculations.
Description of Change
Replace the hardcoded vertical direction with a dynamic call that retrieves the actual scroll direction from the controller. This ensures that horizontal layouts receive the correct scroll position values.
Fix reference
I have fixed the issue in the same way as CV1, by referring to the following code.
