Checkbox - Xamarin Forms does not have even Checkboxes ?!

I am really frustrated now. I've begin a hard transition from Delphi to Xamarin, but finally it turns out that Xamarin Forms is some sort of void of controls.
There is some fragments written freely as open source but nothing seriously supported, and the worse of all - it lack basic controls like CheckBoxes , Radio Buttons and so on and on.
Is this correct or I am doing something wrong ?!
