Summary: - `__Internal` https://developer.xamarin.com/guides/ios/advanced_topics/native_interop/#Static_Libraries > Since you can only use static libraries on iOS, there is no external shared library to link with, so the path parameter in the DllImport attribute needs to use the special name __Internal (note the double underscore characters at the start of the name) as opposed to the path name. - `__IOS__` https://developer.xamarin.com/guides/cross-platform/application_fundamentals/building_cross_platform_applications/part_4_-_platform_divergence_abstraction_divergent_implementation/#iOS > Xamarin.iOS defines __IOS__ which you can use to detect iOS devices.
