How to import opencv2 framework in iOS Swift

I downloaded the latest pre-built opencv2.framework from the OpenCV SourceForge page. then in Xcode6-Beta3, I added opencv2.framework as a required linked framework under the "General" tab of my Swift project settings:

enter image description here

This is the structure of the framework after the framework is added to the project:

If this was a Objective-C project I could add the following import statement:

#ifdef __cplusplus
#import <opencv2/opencv.hpp>
#endif

In my ViewController.swift file, if I do something similar I get a "no such module" error:

enter image description here

I tried the following variations that result in an error:

import opencv2/opencv.hpp
import opencv2/opencv
import opencv
import "opencv2/opencv.hpp"
import <opencv2/opencv>

What is the correct way to import opencv in to my Swift project?

It's easiest if you start with a simple project all ready to compile and run out of the box.

This xcode project works with Swift, XCode 6.1, OpenCV 2, and is MIT licensed: http://whitneyland.com/2014/10/opencv-swift.html

Here's one I haven't tried yet but there are so few still it's worth looking at: https://github.com/foundry/OpenCVSwiftStitch

You will need to create a bridge from C++ to Objective C or plain C. After that, you will need to include/import the bridge's header into an "Objective-C Bridging Header", which Xcode should have generated when you added a Swift source file in an existing project.
