Challenge

Your goal is to build an app that asks users to import a picture from their photo library, then attach a name to whatever they imported. The full collection of pictures they name should be shown in a List, and tapping an item in the list should show a detail screen with a larger version of the picture.

Breaking it down, you should:

• Wrap PHPickerViewController so it can be used to select photos.

ImagePicker

• Detect when a new photo is imported, and immediately ask the user to name the photo.
