What does xamarin ios compile down to?


Asked by Desmond Cisneros on Dec 15, 2021 iOS Development Manual



Xamarin.iOS applications run within the Mono execution environment, and use full Ahead of Time (AOT) compilation to compile C# code to ARM assembly language. This runs side-by-side with the Objective-C Runtime .
In respect to this,
The Xamarin.iOS compiler, smsc, takes source code and compiles it into an intermediate language, ECMA CIL (common intermediate language), however it does not produce ECMA ABI compatible binaries unlike the normal mono compiler, gmcs or dmsc.
Consequently, However, there is a security restriction on iOS, set by Apple, which disallows the execution of dynamically generated code on a device. To ensure that we adhere to these safety protocols, Xamarin.iOS instead uses an Ahead of Time (AOT) compiler to compile the managed code.
Likewise,
In Mac machine, go to Xamarin Studio and select Xamarin Studio Menu >> Click About Xamarin Studio >> click Show details. How to Update Xamarin.Ios in Mac and Windows? Mac Machine Go to Xamarin Studio and Click on “Check for Update” and Update. Windows Machine Go to Visual Studio >> Tools >> extensions and updates.
Indeed,
Xamarin.iOS contains definitions for every single iOS API. You can browse through any of these on the MaciOS github repo. These definitions contain interfaces with attributes, as well as any necessary methods and properties. For example, the following code is used to define a UIToolbar in the UIKit namespace.
