:+1: nice work. With this assignment, we've now explored all the main patterns for building MVC clients! If this were 2009, you would be well on your way to building most apps that you could find in the app store. Over the next few weeks, we'll be focusing on custom views and view controllers to implement the interactions and visual effects that we find in more modern iOS apps.

Here's a checklist of things that I'm looking for in this project. You should review the checklist, and make any changes to your project, if necessary.

• In Objective-C, review your .h files. Your classes should reveal a minimum interface and only expose things that must be used by other classes.
• Each .xib file or Storyboard scene should have Auto Layout constraints specified for each view.
• There should be no yellow Auto Layout warnings, even if the layout seems to work. Auto Layout warnings are like having bad HTML. The browser will try to render it, and it might even look right, but it won't be fully predictable.
• If you're using Objective-C, you can consider using Mantle, a lightweight ORM that eliminates a lot of boilerplate. It's also compatible with Core Data if your project requires that.
