Start with Swift because it's easier. Move to Objective-C when you are ready for lower level hacking. It's the same trajectory we all followed: first learning BASIC, then doing some grovelling in assembly, then moving to something like C or pascal.

When Swift is done... there will be nothing it can't do that Objective-C can.

Swift is not going to be just the beginner language for Mac and iOS programming.... it is going to be THE language for them in a few years

Highly agree. It will grow mature in time (probably a lot faster than iOS did - 30 years) and will feature a lot of new and useful paradigms.
