:+1: nice work. The point of this homework was to explore a simple example of a full MVC application with a RESTful API. For each point in the homework feedback checklist, I'll either confirm that you're on the right track with the implementation, or I'll provide some feedback:

• You should declare all unnecessarily public properties as private for better encapsulation.
• Note that you should resolve all the Auto Layout constraint warnings in your nibs.
• 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 shoud 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 post tweet insertion into the feed. In real MVC apps, the more polished experiences have to do a certain amount of local object management to make a fully seamless experience.

In general, you should challenge yourself to create visually polished applications. That's where you'll find all the rough edges of the iOS framework and earn the next level of mastery.
