I can able to see this the App center. When ever we are working without grouping the collectionview is working fine.
The production application is working fine, without any code changes in our application the collectionview is started crashing when grouping is enabled from the recent iOS version release.
Expecting a quick support as its road block for our upcoming release...
SIGABRT: Objective-C exception thrown. Name: NSInternalInconsistencyException Reason: Expected dequeued view to be returned to the collection view in preparation for display. When the collection view's data source is asked to provide a view for a given index path, ensure that a single view is dequeued and returned to the collection view. Avoid dequeuing views without a request from the collection view. For retrieving an existing view in the collection view, use -[UICollectionView cellForItemAtIndexPath:] or -[UICollectionView supplementaryViewForElementKind:atIndexPath:].

Does this problem only occur in AppCenter builds? If so, it is more recommended that you report this problem to AppCenter Repo.

For further investigation, could you please provide the following information?
- The Maui Version.
- Does this issue trigger on both the simulator and a physical device?
- Could you please provide specific steps to reproduce this issue?
- I noticed that someone reported in Github that CollectionView grouping in iOS 18 will cause the program to crash CollectionView with IsGrouped="True" throws NSInternalInconsistencyException with iOS 18 SDK #24971. You can resolve this issue by rolling back the version.
Hi, I have found a solution to this problem for anyone who is still struggling. All I had to do to get this to work is to add a few packages to the main project csproj. These are the packages that I added: PackageReference Include="Microsoft.Maui.Controls" Version="8.0.92" PackageReference Include="Microsoft.Maui.Controls.Compatibility" Version="8.0.92" PackageReference Include="Microsoft.Maui.Controls.Core" Version="8.0.92" PackageReference Include="Microsoft.Maui.Controls.Xaml" Version="8.0.92" PackageReference Include="Microsoft.Maui.Controls.Build.Tasks" Version="8.0.92" PackageReference Include="Microsoft.Extensions.Configuration" Version="8.0.0" Once you’ve added these packages, do a clean, delete bin and obj, launch visual studio, build the project and run it. This resolved my Collectionview IsGrouped issue for iOS 18.0, I hope it resolves yours too.
Your prompt reply will be highly appreciated.
