Objective-C is a great language; at least a lot of us who have been developing in it for years think so. We're excited about Swift because although ObjC has modernized a great deal, there are limitations to how far it can be pushed. Swift's clean block syntax is a good example here. Objective-C, if you're not turned off by the syntax, can be a joy to program in.
It doesn't even have namespaces. ARC basically made "struct" obsolete (goodbye easy literal data instatiatons), and it doesn't have a lot of the things programmers have come to expect even in compiled languages these days. Now don't get me wrong, for a 30 year old language, it's pretty good, but calling it great may be a little over stated.
I don't mind the syntax, but I don't think it's the nicest language out there feature wise.
