Is iOS still at the experimental stage?

I want to use it on Net.iOS. Where can I get a demo? I only see the Android demo.
I'm running the official demo on the MacOS it works fine but I can't find any documents on iOS. how should I begin?
I don't know how to get get `GL` instance on iOS. Create `IWindow` or `IView` will crash.

```
var options = ViewOptions.Default;
options.API = new GraphicsAPI(ContextAPI.OpenGLES, ContextProfile.Compatability, ContextFlags.Default, new APIVersion(1, 0));
var view = Silk.NET.Windowing.Window.GetView(options);
var window = Silk.NET.Windowing.Window.Create(new WindowOptions(options));
var gl = GL.GetApi(view);
```

### Package List
```
Silk.NET.Windowing
