Xamarin.Forms 2.0.0.6482 Breaks the SearchBar Text and Placeholder Text on iOS

I updated my app in development to use Xamarin Forms 2.0 and the placeholder font for a SearchBar became darker and when typing, it is invisible. Here's some basic sample code to recreate the issue:

public App()
{
// The root page of your application
MainPage = new ContentPage {
Content = new StackLayout {
VerticalOptions = LayoutOptions.Center,
Children = {
new SearchBar{
},
new Label {
XAlign = TextAlignment.Center,
Text = "Welcome to Xamarin Forms!"
}
}
}
};
}

I've verified this on iOS 6s and 4s. The problem does not occur on Android. Screenshots are attached.
