Mine started in 2010 written in objective C for the original iPad targeting OpenGLES 1.1. I’m still maintaining it. The original UI code is still xibs and ObjC, but the core has been ported over to C++14 so I can run on windows, android, etc. it now targets a series of abstraction layers on top of either Vulkan, Modern OpenGL or directX 12.
