You can use a mixture of Swift and Objective-C in a single project, and either language can call APIs implemented in the other.

This community has had substantial input into the direction of Swift, and will continue to shape the language in the future.
Despite the challenges imposed by a changing language, Swift shows great promise and rapid uptake. It follows on from the company’s other major developer tools initiatives, including LLVM, Clang, LLDB, ARC, and a series of extensions to Objective-C, and it’s clear that Apple sees it as ...
