The metal view backing the MoltenVK compatibility wrapper is written in Obj-C. It would have been possible to use the Objective-C runtime in C++ but the code is less performant (the symbol binding is done at first use instead of the beginning of the program) and actually harder to get right. Note that MoltenVK is not linked to the loader, so the libMoltenVK.dylib object must be available for loading.
