Problems with setting focus in iOS Xamarin forms shared projects

I'm trying to change focus from one entry to a different entry. When I tap in the first entry I have a focus in handler set the focus to the second entry. This works in Android but fails to move the cursor in iOS. I can tell that the focus in event fires for the second entry but the cursor remains in the first entry. Is this a bug?

firstEntry.Focused += (sender, e) =>
{
secondEntry.Focus();
};
