What is native?
The Anatomy of a Native App Native User Interfaces Native
API Access Native Performance
The Write Once, Run Anywhere Approach Lowest Common Denominator
The Xamarin Approach Native Apps, with Shared Code
Native Performance Xamarin.iOS does full Ahead Of Time (AOT) compilation
to produce an ARM binary for Apple’s App Store. Xamarin.Android takes advantage of Just In Time (JIT) compilation on the Android device.
TL;DR Anything you can do in Objective-C, Swift, or Java
can be done in C# or F# with Xamarin
