[iOS] CollectionView containing a Footer and a Border with StrokeThickness set to decimal value crashes on scroll #20294
Description
Description
If CollectionView has the following:
- Enough item elements to be scrollable (vertically)
- <CollectionView.Footer> element. I have just a content view of a certain height.
<CollectionView.Footer>
<ContentView HeightRequest="100"></ContentView>
</CollectionView.Footer>
- Each item contains a Border with StrokeThickness set to a decimal value (0.6 for instance)
<CollectionView.ItemTemplate>
<DataTemplate x:DataType="x:String">
<Border StrokeThickness="0.6">
<Label
Text="{Binding}"
FontSize="20"/>
</Border>
</DataTemplate>
</CollectionView.ItemTemplate>
then when you scroll up and then down the app crashes becasue of
Fatal error: <UICollectionView 0x28398dec0> is stuck in its recursive layout loop.
Full code is linked below.
This occurs only in iOS and maui version 8.0.6

Did you find any workaround?
I found three options to choose from:
-
Downgrading to maui 8.0.3
-
Getting rid of the CollectionView Footer
-
Using only whole number for the StrokeThickness value, such as 1
Relevant log output
UIKitCore/_UICollectionViewFeedbackLoopDebugger.swift:87: Fatal error: <UICollectionView 0x28398dec0> is stuck in its recursive layout loop. This can happen when self-sizing views do not return consistent sizes, or the collection views frame/bounds/contentOffset is being constantly adjusted. To debug this issue, check the Console app for logs in the "UICollectionViewFeedbackLoopDebugger" category.
