I developed a software that provides some augmented reality. Now I want it to work on IOS devices (mostly iPad). All my tracking functions are in C++, do I have any way to make them work on IOS devices ? Is it possible to create a bridge between a c++ DLL and Swift ? if it is, how can I do that ?

Thank you really much.

    Graphic functions are a perfect example of why what you trying to is completely impossible: if you use DirectX functions in the DLL how is that supposed to work on iOS? – luk2302 Nov 28 '16 at 18:34
  • Just because it's a DLL doesn't mean it's using DirectX, it *could* be using OpenGL – Alexander Nov 28 '16 at 18:39

    More Information is needed. On what platform? A Windows DLL or a "dynamically loaded library" in the general sense? What kind of functions? – But generally, you can call C functions from Swift, but not C++ functions. – Martin R Nov 28 '16 at 18:39

Hi Saadi the answer is no.

Because DLL stands for Dynamic Linked Library and it is a Window Based Way to Pack Functionality.

Once you are in Swift I suposed you are in Apple Enviroment, so this will not work at all.

if you have the source-code of your DLL, the best you can do is to try to adapt from the source code, and compile it to Apple Platform, and then use it.

    Swift does not necessarily means Apple. It works on [linux](https://www.raywenderlich.com/122189/introduction-to-open-source-swift-on-linux) and there is a port on [windows](https://swiftforwindows.codeplex.com/) too. It should be able to work, but I believe you will have to do this on a windows machine and I have not done windows dev in 10+years. – Arnaud Thiercelin Nov 28 '16 at 18:36
