CollectionView - Issue when update ItemsLayout programmatically - xamarin

Question

I am updating the CollectionView.ItemsLayout programmatically after binding the item source, and it works fine on Android but not on iOS. The iOS app does not throw any exception/error, but the application hangs and when I look at the output window I got the message below:
An attempt to update layout information was detected while already in the process of computing the layout (i.e. reentrant call). This will result in unexpected behaviour or a crash. This may happen if a layout pass is triggered while calling out to a delegate. UICollectionViewFlowLayout instance is (<Xamarin_Forms_Platform_iOS_GridViewLayout: 0x7fb2940ec010>)
An attempt to prepare a layout while a prepareLayout call was already in progress (i.e. reentrant call) has been ignored. Please file a bug. UICollectionView instance is (<UICollectionView: 0x7f9e68a73000; frame = (0 0; 355 360); clipsToBounds = YES; autoresize = W+H; gestureRecognizers = <NSArray: 0x600003039c20>; layer = <CALayer: 0x600007e6e180>; contentOffset: {0, 0}; contentSize: {1, 0}; adjustedContentInset: {0, 0, 0, 0}; layout: <Xamarin_Forms_Platform_iOS_GridViewLayout: 0x7f9e647972e0>; dataSource: <Xamarin_Forms_Platform_iOS_GroupableItemsViewController_1: 0x7f9e64797940>>)
