> In fact, Swift is really built on top of Objective-C, somewhat similar to how Objective-C is built on top of C, and somewhat similar to how C is built on top of assembly. Apparently, this is not exactly the case: > not [Objective-C] under the hood so much as on the side. Swift has its own (relatively minimal) runtime. [1] > Swift interoperates with the ObjC runtime. It's not dependent on it. [2] I believe this means that one day Swift could drop the Objective-C runtime & dependencies, perhaps in favor of a Cocoa evolution that doesn't rely on KVO, selectors, etc. [1]: https://twitter.com/jckarter/status/475503398087708672
