5578 # Mono.Native Support
5579 # -------------------
5580 # Mono.Native is the new name for both System.Native and System.Security.Cryptography.Apple.
5581 # It is built as a stand-alone shared library and not bundled with the runtime because we
5582 # may need to build two different versions of it.
5583 #
5584 # Starting with macOS 10.12+ and iOS 10+, Apple introduced a new Unified API for some of the
5585 # crypto primitives that we're using as part of System.Security.Cryptography.Apple.
5586 #
5587 # On Desktop, we can check at runtime whether the OS version is recent enough and switch
5588 # implementation accordingly.  We build a single `libmono_native` shared library.
5589 #
5590 # However, on Mobile we cannot have any undefined symbols as this would break Bitcode.
5591 #
5592 # During the mobile build, we are called with `CC` containing an explicit minium version flag,
5593 # which is eiter `-mmacosx-version-min=`, `-mios-simulator-version-min=` or `-miphoneos-version-min=`
5594 # depending on platform.
5595 #
5596 # We build two versions of the shared library:
5597 # - `libmono_native_compat` is built with whichever minimum version is passed to us via `CC`.
5598 # - `libmono_native_unifed` is built with the minimum version set to macOS 10.12+ / iOS 10+.
5599 #
5600 # For testing purpuses, there is a function called `mono_native_get_platform_type ()`
5601 # (see mono/native/mono-native-platform.c), which returns a `MonoNativePlatformType` enum value.
5602 # There is also `Mono.MonoNativePlatform.GetPlatformType ()` (see mcs/class/System/Mono/MonoNativePlatform.cs).
5603 #
5604 # This can be called by automated tests both to ensure that the library has been correctly installed and also
5605 # to verify that it's the correct version of it.
5606 #
5607
5608 # `target_ios=yes` does not detect watch devices and fails when cross-compiling
