Xamarin applications can also be described as native because they use native UI components and APIs provided by the target platform, whether it is Android or iOS. Xamarin allows developers to write code in C#, which is then compiled to native code for each platform. This means that the application's UI is rendered using native components rather than web technologies, which gives it a more native look and feel.

Xamarin also provides a set of platform-specific APIs that allow developers to access native features such as camera, accelerometer, and GPS. This level of access to platform-specific features ensures that Xamarin applications are able to offer a truly native experience to users.

Therefore, Xamarin applications can be considered as a native approach to building mobile applications. However, like React Native, Xamarin does introduce some performance overhead due to the use of a bridge to communicate between the C# code and the native components. Nonetheless, Xamarin remains a powerful tool for building high-quality, performant mobile applications that feel native on both Android and iOS platforms

Compilation

Xamarin uses a combination of ahead-of-time (AOT) and just-in-time (JIT) compilation to compile C# code into native code for the target platform.

When building a Xamarin app, the C# code is compiled into intermediate language (IL) code, which is then compiled to native code using an AOT compiler. The AOT compilation produces optimized, native machine code that runs directly on the target platform's processor, resulting in fast and responsive applications.

For iOS, Xamarin uses the Xamarin.iOS runtime, which includes a just-in-time (JIT) compiler that optimizes the IL code at runtime. The JIT compiler can be disabled for release builds, in which case the AOT compiler is used to produce optimized native code ahead of time.

For Android, Xamarin uses the Xamarin.Android runtime, which includes an AOT compiler that compiles the IL code to native code ahead of time.

Xamarin also includes a cross-platform development toolkit called Xamarin.Forms, which allows developers to build user interfaces that can be shared across multiple platforms. Xamarin.Forms uses a markup language called XAML to define the user interface elements, which are then rendered natively on each platform.

Overall, Xamarin compiles C# code into optimized, native machine code for iOS and Android using a combination of ahead-of-time (AOT) and just-in-time (JIT) compilation. This approach provides high-performance applications with fast startup times and responsive user interfaces. Xamarin also includes a cross-platform development toolkit called Xamarin.Forms, which allows developers to build shared user interfaces across multiple platforms.
