If you need to be nitpicky about squeezing every last bit of performance out, then Objective-C is still useful, especially given you can just drop down to C in the same source files. I've become a big "C is bad and C lovers should feel bad" guy in recent years, but I can't ignore the "simplicity" (for some experience level definiton of simplicity) and speed of the old tools.
