:+1: Nice work Greyson. The point of this homework was to explore an example of a full MVC application with a RESTful API. A few notes after checking out the code:

• When the user creates a new tweet, it's a good time to use the delegate pattern to communicate this back to the TweetsViewController.
• AFNetworking has an image cache so you don't need to worry about performing a network fetch each time you try to load an image that you've already fetched.
• Good coding style for the properties. The compiler generates important things in the getters and setters that get circumvented when the instance variables are used directly (the variables that are prefixed with underscore). Always use self.property to access a property.
• You should move all unnecessarily public properties to the private class extension in the .m file.
• Note that you should try handling the conditionally present retweet label in the cells. This is a situation where its not possible to specify the behavior that you want solely using Interface Builder.
• You should try setting up the controls within the Tweet cells. It can sometimes be hard to have a clean design for embedded controls because it usually involves cumbersome plumbing. This is an instance where I think having the model handle the network action helps greatly simplify the implementation.
• You should try implementing the compose a new tweet insertion into the feed without a network request. In real MVC apps, the more polished experiences have to do a certain amount of local object management to make a fully seamless experience.

We have a detailed Project 3 Feedback Guide which covers the most common points we see for this project. Read through the feedback guide point-by-point to determine other ways you could improve your submission. You should consider going back and implementing applicable feedback as well.

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 most modern iOS apps.
