I've been writing Objective-C for a long time now, and have shipped a fair number of iOS apps. It's a beautiful language in my opinion, if you can get passed the syntax (harder for those who lack a "beginners mind" and are used to a certain way of doing things.) To answer your question, it really depends on your goals. If you're looking to write your own apps, and you're not under any time pressure, I'd say start with swift. Apple will push the adoption curve _hard_, they always do. If you're looking to get a job as an iOS developer in the next year or so, Objective-C isn't going anywhere. Big organizations in particular will not be rewriting their apps from the ground up, and there will be legacy code to maintain for years to come. I know of some big projects that were still avoiding ARC for quite a long time... No matter what, I'd learn Swift _now_, but if you can spare the time I'd say do yourself a favor and learn both. Objective-C has a lot of great concepts, and they're totally worth learning. And it will make understanding the Cocoa and UIKit frameworks a bit easier as well. Good luck!
