I mean sometime in the future will probably be pretty far away for Obj-C developers.
“Objective-C is not going away. We still love Objective-C as a language; we still very much depend on Objective-C and do a tremendous amount of work in Objective-C here internally at Apple,” Federighi told Ars. “We’ll be supporting Objective-C and continuing to evolve it as necessary to fit into this evolving world. We do think that Swift is the language that we recommend for new developers to our platform who are investing for the future and building new apps. We think Swift is absolutely the right place to start. But we’ll continue to maintain, advance, and support Objective-C for as far as we can see.”
