For game programming where you might want cross platform look at C++ and Cocos2D-x. Otherwise my advice is to learn Objective C, even if you learn Swift you really still need to know Objective C. Swift is not really ready for production apps and learning new stuff is hard enough without having to sort out bugs in the language that you don't really understand complete alongside your own bugs. There's tons of information on how to do things in Objective C not so much with Swift, it's still too new.
