Could not initialize an instance of the type 'UIKit.UIImage'

[jbarreira]

I'm trying to add TEditor to my Xamarin application (not using Xamarin.Forms) and when calling the
await CrossTEditor.Current.ShowTEditor it's giving me this error:

System.Exception: Could not initialize an instance of the type 'UIKit.UIImage': the native 'initWithContentsOfFile:' method returned nil.
It is possible to ignore this condition by setting MonoTouch.ObjCRuntime.Class.ThrowOnInitFailure to false.

It seems that [email protected] cannot be found. Do you know any workaround?
Thanks!

Can you try to rebuild the project? It's wired, that images also in the source code.
