Thanks Vlad!!

Hopefully this'll be the last time we have to update nfloat 😅

And thanks for fixing our typos!!

Let's just use .First() since it's the same as .FirstOrDefault() ?? throw new NullReferenceException()

Suggested change

	public UIView ParentView => UIApplication.SharedApplication.ConnectedScenes.ToArray()
	.Where(x => x.ActivationState == UISceneActivationState.ForegroundActive)
	.Select(x => x as UIWindowScene)
	.FirstOrDefault()?
	.Windows.FirstOrDefault(x => x.IsKeyWindow) ?? throw new NullReferenceException("KeyWindow is not found");
	public UIView ParentView => UIApplication.SharedApplication.ConnectedScenes.ToArray()
	.Where(x => x.ActivationState == UISceneActivationState.ForegroundActive)
	.Select(x => x as UIWindowScene)
	.First()
	.Windows.First(x => x.IsKeyWindow);

Or, another idea (and maybe this one is better because it'll help users more easily track down the Exception), we throw InvalidOperationException:

Suggested change

	public UIView ParentView => UIApplication.SharedApplication.ConnectedScenes.ToArray()
	.Where(x => x.ActivationState == UISceneActivationState.ForegroundActive)
	.Select(x => x as UIWindowScene)
	.FirstOrDefault()?
	.Windows.FirstOrDefault(x => x.IsKeyWindow) ?? throw new NullReferenceException("KeyWindow is not found");
	public UIView ParentView => UIApplication.SharedApplication.ConnectedScenes.ToArray()
	.Where(x => x.ActivationState == UISceneActivationState.ForegroundActive)
	.Select(x => x as UIWindowScene)
	.FirstOrDefault()?
	.Windows.FirstOrDefault(x => x.IsKeyWindow) ?? throw new InvalidOperationException("KeyWindow is not found");

Do we need this ToArray call?

[VladislavAntonyuk]

yes, the type of ConnectedScenes is NSSet<UIScene> and doesn't support Linq

[VladislavAntonyuk]

We cannot use First() because we cast to UIWindowsScene and still need to check for null. I will change it to InvalidOperationException
