[Bug] UINavigationBar.Appearance.BarTintColor not set

[SandraHicks]

Description

After upgrading Xamarin.Forms from 4.8.0.1364 to 5.0.0.2012, I cannot set the UINavigationBar.Appearance.BarTintColor in my AppDelegate.cs FinishedLaunching Method. Any attempt is ignored.

Ususally, I set it from an image after loading the Application:

global::Xamarin.Forms.Forms.Init();

Forms9Patch.iOS.Settings.Initialize(this);

LoadApplication(new App((int)(UIScreen.MainScreen.Bounds.Height), (int)(UIScreen.MainScreen.Bounds.Width), fromPush));

var image = UIImage.FromFile("toolbar_image.png");
                if (image != null)
                    UINavigationBar.Appearance.BarTintColor = UIColor.FromPatternImage(image);

Nevertheless, even setting a color is ignored, it just stays white as the background:

UINavigationBar.Appearance.BarTintColor = UIColor.Blue;

There is no other place in my code where I set it for iOS.

Does anyone else encounter this issue? Is there any workaround? I cannot stay on 4.8 much longer.

Steps to Reproduce

1. Try to set the UINavigationBar.Appearance.BarTintColor in AppDelegate FinishedLaunching

Expected Behavior

Color is set (or image is displayed)

Actual Behavior

Just the background white is showing

I am having the same problem. Affected iPhone 8.

[antiGithub]

Same problem (background white) with iPhone 6s iOS 14.4 and Xamarin.Forms 5.0.0.2012

If Running on Device in Win VS2019 via attached iPhone on connected mac then background color will be black?
