6249 # -------------------
6250 # Mono.Native is the new name for both System.Native and System.Security.Cryptography.Apple.
6251 # It is built as a stand-alone shared library and not bundled with the runtime because we
6252 # may need to build two different versions of it.
6254 # Starting with macOS 10.12+ and iOS 10+, Apple introduced a new Unified API for some of the
6255 # crypto primitives that we're using as part of System.Security.Cryptography.Apple.
6257 # On Desktop, we can check at runtime whether the OS version is recent enough and switch
6258 # implementation accordingly.  We build a single `libmono-native` shared library.
6260 # However, on Mobile we cannot have any undefined symbols as this would break Bitcode.
6262 # During the mobile build, we are called with `CFLAGS` containing an explicit minium version flag,
6263 # which is eiter `-mmacosx-version-min=`, `-mios-simulator-version-min=` or `-miphoneos-version-min=`
6264 # depending on platform.
6266 # We build two versions of the shared library:
6267 # - `libmono-native-compat` is built with whichever minimum version is passed to us via `CFLAGS`.
6268 # - `libmono-native-unifed` is built with the minimum version set to macOS 10.12+ / iOS 10+.
6270 # For testing purpuses, there is a function called `mono_native_get_platform_type ()`
6271 # (see mono/native/mono-native-platform.c), which returns a `MonoNativePlatformType` enum value.
6272 # There is also `Mono.MonoNativePlatform.GetPlatformType ()` (see mcs/class/corlib/Test/Mono/MonoNativePlatform.cs).
6274 # This can be called by automated tests both to ensure that the library has been correctly installed and also
6275 # to verify that it's the correct version of it.
