Join David Okun for an in-depth discussion in this video Refactoring your sample application, part of Swift: Writing Reusable Frameworks.
- 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.…
Along the way, he explains the differences and nuances between writing code for an application and for a reusable framework, as well as some of the fundamentals of AVFoundation, one of the core camera frameworks in iOS. David also shows how to refactor your code, understand Swift access control, develop an interface, and handle memory leaks, so your framework is ready to share with other developers.
