Bug[989598] - SfPullToRefresh gets stuck during pulling inside CollectionView, SfListView or SfDataGrid in ios

[Monika4841]

Bug Description

• On iOS devices using .NET MAUI 10, the SfPullToRefresh control starts the progress bar when pulling down to refresh, but it gets stuck and doesn't complete the refresh when used with CollectionView, SfListView or DataGrid.

Root Cause

• The OnTouch method is not triggered on iOS because the PullToRefresh gesture is not recognized. Once the OnTouch method is called, the pointer action should update to the Moved state. In this state, the progress rate is expected to increase. Therefore, for the refresh functionality to work correctly. So, the OnTouch method must be triggered.

Solution Description

• In the ShouldRecognizeSimultaneousGesture method, returning false allows only one gesture to be recognized. In .NET 9, the PullToRefresh gesture was recognized correctly, and the OnTouch method was triggered as expected.
• However, in .NET 10 on iOS, returning false causes the system to recognize only the ScrollView gesture in CollectionView, SfListView or DataGrid, and not the PullToRefresh gesture. As a result, the refresh operation gets stuck because the OnTouch method is never triggered.
• By returning true in the ShouldRecognizeSimultaneousGesture method, both gestures are now recognized simultaneously, allowing the PullToRefresh functionality to work correctly.

Pull Request Overview

This PR fixes a bug in .NET MAUI 10 where the SfPullToRefresh control gets stuck during the refresh operation when used with CollectionView, SfListView, or SfDataGrid on iOS and macOS platforms.

Key Changes:

• Added conditional logic for .NET 10+ on iOS to allow simultaneous recognition of both the PullToRefresh gesture and the ScrollView gesture, resolving a regression where returning false caused only the ScrollView gesture to be recognized, blocking the PullToRefresh functionality.

The conditional compilation directive only includes IOS, but since this fix is tested on both iOS and macOS (as mentioned in the PR checklist), it should also include MACCATALYST. MacCatalyst apps also use UIKit and would likely experience the same gesture recognition issue on .NET 10.

Consider changing to:

#if NET10_0_OR_GREATER && (IOS || MACCATALYST)

This pattern is consistent with other conditional compilation in the codebase (e.g., Accordion/Helper/AccordionScrollView.cs:9).

Suggested change

	#if NET10_0_OR_GREATER && IOS
	#if NET10_0_OR_GREATER && (IOS || MACCATALYST)
