Apple introduced with iOS 11 a new UI in particular for larger titles: if you open your email, you see at the top a large title. That sit in the Navigation Bar and can be scrolled away when more space is needed. We can enable large titles with a renderer.

For this example, I only created a new project and added the following renderer in the iOS project under Renderers folder. You can easily add to all your solution the following renderer in your iOS project:

using System;
using YourProject.iOS.Renderers;
using UIKit;
using Xamarin.Forms;
using Xamarin.Forms.Platform.iOS;

[assembly: ExportRenderer(typeof(NavigationPage), 
namespace YourProject.iOS.Renderers
    public class CustomNavigationRenderer : NavigationRenderer
        protected override void OnElementChanged(
                                VisualElementChangedEventArgs e)

            // Enables iOS 11 new Large Titles system-wide
            if (UIDevice.CurrentDevice.CheckSystemVersion(11, 0))
                // Enable Large Titles
                NavigationBar.PrefersLargeTitles = true;

                // Adopt same TextAttributes as for normal titles
                // beacuse Xamarin.Forms NavigationPage
                // does not have a dedicated property for this yet
                UINavigationBar.Appearance.LargeTitleTextAttributes =
                    new UIStringAttributes { 
                            ForegroundColor = 
                               (Element as NavigationPage)?.
                               BarTextColor.ToUIColor() };
