being hit when the bug appears... InsertCore AddCore 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

@ajpinedam this may be a related reason for your issue.
