Refactoring your sample application

- We've done a lot of great work so far…to make sure that we get…a still image out of our camera object.…Now let's finally take that image,…return it out of our framework,…and add it to our sample application.…First, we know that we have…a handle on our image here…as it's returned from our camera object.…We need to make sure that…we're adding a delegate function…to return that out of our view controller…and back to our sample application.…To do this, go ahead and scroll…to the top of cameraviewcontroller.swift…inside your reusable framework.…Underneath the declaration for cancelButtonTapped,…add another function.…

We'll call this one "stillImageCaptured"…and we'll pass in the controller…of type CameriaViewController…and we'll also include an image…of type UIImage.…Scroll back down to your extension,…where you're handling functions from CameraDelegate…and go inside the function for stillImageCaptured.…Delete your print statement…and if you had a break point set here previously,…make sure that get rid of that as well.…
