## What it is
Open-source .NET bindings of the Apple SDKs enabling native iOS, Mac Catalyst, macOS, and tvOS development in C# and other .NET languages. It is the successor to Xamarin.iOS/Xamarin.Mac and underpins the Apple platform support in .NET MAUI.

## Use cases
- build native iOS apps in C#
- create macOS apps with .NET
- develop tvOS or watchOS apps using C#
- use Apple frameworks from C# code
- migrate Xamarin.iOS projects to .NET
- build MAUI apps targeting Apple platforms

## When to choose
- you want native Apple platform apps written in C#/.NET
- you need direct bindings to Apple SDK APIs from managed code
- you are building or migrating .NET MAUI apps for iOS/macOS

## When to avoid
- you only target Android or Windows
- you prefer Swift/Objective-C native development
- you rely on legacy Xamarin support, which ended May 2024
