I don&#x27;t think Unity does it any more, but it wasn&#x27;t that long ago when Unity used Xamarin to be able to run on iOS, Android and PS4. Now they do it with il2cpp I think.<p>Also, it seems you have no idea what you&#x27;re talking about. Xamarin gives you access to the same native APIs that you use when developing a native app. You still need to know the native API if you want to build an iOS app. Xamarin.Forms helps, but doesn&#x27;t support everything.
