[iOS] ScrollView Orientation set to Horizontal allows both horizontal and vertical scrolling .

[NafeelaNazhir]

Description

When setting the Orientation property of a ScrollView to Horizontal in .NET MAUI, the expected behavior is that the content should only scroll horizontally. However, on iOS, the ScrollView allows both horizontal and vertical scrolling, which is inconsistent with the expected and documented behavior.

Expected Output	Actual Output
Screen.Recording.2025-06-19.at.5.54.19.PM.mov	Screen.Recording.2025-06-19.at.5.47.06.PM.mov

Steps to Reproduce

1. Run the attached sample ScrollViewOrientation.zip
2. Set ScrollView Orientation as Horizontal.
3. Select the content and observe the orientation.

Expected Behavior:
The content should only scroll horizontally; vertical scrolling should be disabled.

Actual Behavior:
The content scrolls both horizontally and vertically on iOS and Catalyst, even though the orientation is set to Horizontal.

Hello here, 👋

iOS has a different behavior than android when it comes to ScrollView, CollectionView, and CarouselView.

As long as the HeightRequest is not set, iOS will tell the UI Control stated above to use the full page.

Make sure the ScrollView is the root when present in the view tree. This means: you first set the ScrollView, then you set up your Grid/StackLayout/...

Avoid using ScrollView inside CollectionView or CollectionView inside ScrollView or CarouselView inside ScrollView. In those cases, it's better to use Grid as parent.

To address the issue, you can use CollectionView to bind your items with ItemTemplate set to LinearItem with Orientation property set to Horizontal
