Is there any way to use metal-cpp in a Swift project? I have a platform layer I've written in Swift that handles Window/View creation, as well as event handling, etc. I've been trying to bridge this layer with my C++ layer as you normally would using a pure C interface, but using Metal instances that cross this boundary just doesn't seem to work. e.g. Currently I initialize a CAMetalLayer for my NSView, setting that as the layer for the view. I've tried passing this Metal layer into my C++ code via a void* pointer through a C interface, and then casting it to a CA::MetalView to be used. When this didn't work, I tried creating the CA::MetalLayer in C++ and passing that back to the Swift layer as a void* pointer, then binding it to a CAMetalLayer type. And of course, this didn't work either. So are the options for metal-cpp to use either Objective-C or just pure C++ (using AppKit.hpp)? Or am I missing something for how to integrate with Swift?

Hi, I trying to use Metal cpp, but I have compile error: ISO C++ requires the name after '::' to be found in the same scope as the name before '::' metal-cpp/Foundation/NSSharedPtr.hpp(162): template <class _Class> _NS_INLINE NS::SharedPtr<_Class>::~SharedPtr() { if (m_pObject) { m_pObject->release(); } } Use of old-style cast metal-cpp/Foundation/NSObject.hpp(149): template <class _Dst> _NS_INLINE _Dst NS::Object::bridgingCast(const void* pObj) { #ifdef __OBJC__ return (__bridge _Dst)pObj; #else return (_Dst)pObj; #endif // __OBJC__ } XCode Project was generated using CMake: target_compile_features(${MODULE_NAME} PRIVATE cxx_std_20) target_compile_options(${MODULE_NAME} PRIVATE "-Wgnu-anonymous-struct" "-Wold-style-cast" "-Wdtor-name" "-Wpedantic" "-Wno-gnu" ) May be need to set some CMake flags for C++ compiler ?

Now the examples of metal-cpp are target on desktop and using AppKit which is not supported on iOS. Is there any tips for developing with metal-cpp on mobile device?
