• Milestone: Projects 10-12

• Details

   - You’ll need to make ViewController build on UITableViewController rather than just UIViewController.
    - Just like in project 10, you should create a custom type that stores an image filename and a caption string, then use either Codable or NSCoding to load and save that.
    - Use a UIAlertController to get the user’s caption for their image – a single text field is enough.
    - You’ll need to design your detail view controller using Interface Builder, then call instantiateViewController to load it when a table view row is tapped.
