Bridge C++ to Swift through Objective-C #20

Open gabimoncha opened 2 years ago

I understand that it's pretty impossible to call call C++ from Swift, but Swift could call ObjC methods. In this article there is an example on how to use ObjC to bridge C++ to Swift and might be a good start to make this library support it too

Thanks for sharing, @gabrielmoncea. Codegen generates .mm files, and I couldn't find an easy way to implement the protocol of the generated code in Swift. Especially since there's a function you must call from our own .mm file that is entirely c++ (the JSI binding itself).

I would love to see a proof of concept with swift + nice binding but couldn't get one working by myself (invested about 2-3 hours in trying and making it happen)
