You can include and use CocoaPods in a swift project.

Objective-C from Swift

To use Objective-C code in swift you need to setup a bridging header to make the Objective-C code visible to Swift.

Add header file to your project (eg. Bridging-Header.h). Set the bridging header in the Build Setings (eg. YourApp/BridgingHeader.h). Then add #includes into the bridging header.

#import <AFNetworking/AFNetworking.h>

Swift from Objective-C

XCode generates a header for you to include, named after your project ProjectName-Swift.h

If a swift class doesn’t subclass an Objective-C object then the Swift class needs to be marked @objc

@objc class YourObject {
  // ...
}
