I have developed my own cross-platform GUI framework in C++ and I am looking to add support for Mac. I have tried to stay as close to the metal as possible, using GDI+ on Windows and X11 / XRender on Linux.
Years ago I had a precursor to this system working with Cocoa and Quartz, which required an interface with some Objective-C code.
In the latest version of Xcode I don't see any options to create an Objective-C application. Should I be creating a Swift application? If so, how do I make that interface with my C++ code? I am not interested in a GUI designer or anything like that because I am writing a general-purpose library. I just need the ability to create OSX windows and draw 2D graphics on them with the low-level system commands.
Please advise.
