Apple did not invented Objective-C. They took it over from NeXT. Which also didn't invent it. Also, since Objective-C is basically just C, you could actually target their platform with plain C if you know what you're doing. Some of the underlying frameworks (e.g. Core Foundation) are actually C APIs.
