For developers who love Xamarin.iOS or Xamarin.Android but struggled enough with Xamarin.Forms...
I just open-sourced 4 years of extensive work resulted in a creation of Fusion framework which is now available under Apache license, version 2.0.
The main idea of the framework was to build a tool that you can learn how to use once and then be able to apply everywhere (iOS and Android, for now) - "Learn once, code everywhere" principle, rather than "Code once, run everywhere". The framework doesn't strictly follow any standard architectural patterns (MVC, MVVM, etc.) but rather violate them as the focus here is on simplifying the development of common tasks.

Here is an example of an app built with the Fusion framework:
