UIView // Abs=[Rect 16.5x16.5@10,119]
^ the UIView is:

when the grid render correctly without the error, the last UIView is no longer present
so the question is who added it? and, what exactly was added?
judging from observation, it seems to be the native text correction overlay
pic: https://i.imgur.com/dMZ2otm.png
but shouldnt it be added under textbox, rather than at the level of textbox..?
^ actually, it happens to both...
this UIView is added and removed, as the textbox receive or lose focus
UIElementCollection:: // none of them are being hit when the bug appears...

it is added by the native, directly into the _shadowChildren (which is the backing store for UIElementCollection _children)
when enumerating, the etor just: _inner.Current as UIElement // from UIElementCollection.Xamarin.cs
so Grid impl need to be shielded from edge cases introduced like this...
To me, I think we should fix it in MoveNext:
https://github.com/unoplatform/uno/blob/9cc1c6633f0731699a99cf6b36f2cf0465eb71aa/src/Uno.UI/UI/Xaml/UIElementCollection.Xamarin.cs#L43
As this enumerator is intended to enumerate UIElements, it should keep moving while current is not UIElement.
Something like:
while (_inner.MoveNext())
{
if (_inner.Current is UIElement) break;
}
i did a null filter in both arrange and measure it works. the grid renders 'n all but there are still warnings from ios:
// same messages repeated 6times
SamplesApp[98188:1921608] [Unknown process name] Error: this application, or a library it uses, has passed an invalid numeric value (NaN, or not-a-number) to CoreGraphics API and this value is being ignored. Please fix this problem.
SamplesApp[98188:1921608] [Unknown process name] If you want to see the backtrace, please set CG_NUMERICS_SHOW_BACKTRACE environmental variable.
filtering in UIEleCol seems like a better idea, but i think we might need also take care of situation where the non-UIElement is in the middle of list(due to for-loop + indexer), and adjust stuff like .Count/.Length too
it is actually a messy situation, it is not just the UIEleCol.Etor.MoveNext that needs to be updated but most accessors like Count, Indexer[int].get from UIEleCol, and potentially mutators like add,insert,remove,etc that need to be updated to ignore the imposter in the source collection
