The Objective-C Bridging Header

If you want to consume Objective-C code from Swift, you'll need to use a [bridging header] (https://developer.apple.com/library/ios/documentation/Swift/Conceptual/BuildingCocoaApps/MixandMatch.html).

If you didn't create one when you first created the project:

This can be done by File -> New -> File ... -> iOS -> Source -> Header File. You'll want to name this file something like YourProject-Bridging-Header.h, but the name doesn't actually affect the build process. You'll need to specify this file as a bridging header in your project's Build Settings.

You will then #import every Objective-C header you want to expose to Swift in this file.
