FFImageLoading fail to load image on iOS after upgrading from 2.1.8 to 2.2.4

Hi,

I have a Xamarin.Forms project where i use FFImageLoading to load an image from a web url applying a CircleTransformation.

This is the init code:

Image = new CachedImage {
	Aspect = Aspect.AspectFill,
	HorizontalOptions = LayoutOptions.CenterAndExpand,
	VerticalOptions = LayoutOptions.CenterAndExpand,
	CacheDuration = TimeSpan.FromDays (30),
	DownsampleUseDipUnits = true,
	DownsampleWidth = size,
	LoadingPlaceholder = DefaultImage,
	ErrorPlaceholder = DefaultImage,
	Transformations = new System.Collections.Generic.List<ITransformation> () {
		new CircleTransformation(),
	},
	TransformPlaceholders = true
};

When i download the data model from my webservice i setup Image.Source = "https://censored/url/of/image.jpg".

With FFIMageLoading.iOS 2.1.8 everything worked, but after the upgrade to 2.2.4 i have the following exceptions: Image loading failed: https://censored/url/of/image.jpg;188x0CircleTransformation,borderSize=0,borderHexColor= System.Exception: Could not initialize an instance of the type 'UIKit.NSDataAsset': the native 'initWithName:' method returned nil. It is possible to ignore this condition by setting MonoTouch.ObjCRuntime.Class.ThrowOnInitFailure to false. and Image loading failed: https://censored/url/of/image.jpg;188x0CircleTransformation,borderSize=0,borderHexColor= UIKit.UIKitThreadAccessException: UIKit Consistency error: you are calling a UIKit method that can only be invoked from the UI thread.

I attach a file with the full stack trace. Thank you for you help.

- Edit - I also tried removing the CircleTransformation but the issue wasn’t there.

I see the same issue using version 2.2.9 throwing UIKitThreadAccessException on iOS 10 when using a LoadingPlaceholder or ErrorPlaceholder from asset catalog

In my case I can confirm that the issue has been resolved in the latest pre-228 release. Thanks for that!!
