This project was built for the tutorial Fun with LLMs: Building a Haiku Maker App with a Vision Model

For the API layer, we’ll define a HaikuGenerator protocol to allow easy swapping between different implementations and make testing easier using Dependency Injection. We’ll mainly use SwiftUI for the UI because it’s quick and straightforward to set up. For the image picker, we’ll use PHPickerViewController instead of UIImagePickerController. Since we only need to select an image (no need for editing or capturing new ones), PHPickerViewController is lighter and easier to configure. Because PHPickerViewController is a UIKit component, we’ll integrate it into SwiftUI using UIViewControllerRepresentable.
