To answer your question, Swift adds an expressiveness for nullability to APIs, more type expressiveness on collection constituents, a better pattern for if/else if/else if/.../else for object-equality testing that mirrors C switch/case, less conversion needed between analogous C types and Cocoa-related types, and with Swift 2, a compiler-supported, single-runtime-coded method to deal with unsupported APIs on older OSes. There are others, by the way.
All of these things can be done with Objective-C and lots of C-based code, but those require comments, extra code, and an understanding on the part of the developer to remember certain patterns whereas with Swift, the compiler enforces these.
One can write object-oriented code that mirrors the functionality of C++ by using structures, function pointers, and multiple synchronized arrays, but when you have a means to do all that for you, you're free to move on to developing what you really want rather than working on the plumbing all the time. Of course, compiler developers must think of these things, but the vast majority of us aren't them.
Disclaimer: I've not jumped onto the Swift bandwagon yet due to a variety of reasons, but I will soon.
