NEW! Master Swift design patterns with my latest book! >>

Setting up

This is a fun, simple and useful project that will let you create an app to help store names of people you've met. If you're a frequent traveller, or perhaps just bad at putting names to faces, this project will be perfect for you.

And yes, you'll be learning lots along the way: this time you'll meet UICollectionViewController, UIImagePickerController, Data, and UUID. Plus you'll get to do more with your old pals CALayer, UIAlertController, and closures. But above all, you're going to learn how to make a new data type from scratch for the first time.

Create a new Single View App project in Xcode, call it Project10, then save it somewhere. This should be second nature to you by now – you're becoming a veteran!
