Nice work! We added this homework so that you'll have the experience building an app that's more similar in complexity to a production app. It's also useful to have practical experience building a container view controller, which is a more advanced topic. The optional account switching feature is interesting because you have to think about how TwitterClient is caching the access token to make sure it works correctly for multiple accounts. Displaying the account switching screen is implemented using custom view controller transitions.

A few notes after checking out the code:

• For TweetTableViewCell.h, you should move all unnecessarily public properties to the private class extension in the .m file.
• You shouldn't access your private instance variable directly (names with underscores). The compiler generates important things in the getters and setters that get circumvented when the instance variables are used directly. Always use self.property to access a property.
• You should always specify Auto Layout constraints in your nibs.
• Nice work specifying the Auto Layout constraints.
• Consider refactoring the profile view controller so that it shares code with the TimelineViewController. There are two general strategies: you can subclass the TimelineViewController or create a separate class called a TimelineController (not a view controller). TimelineController is a dataSource and a delegate to a UITableView and knows how to show a feed of tweets.
• For the custom cells that you added, make sure that it only exposes a property for the data. In the private implementation, it should configure the views.
• You should consider what a more generic design for your hamburger controller might look like. Right now, it's tightly bound to this Twitter application.
• Great job with the blurred header. There are several approaches here that are all valid. You can implement the header has a table header, a section header, or a cell. My preferred approach is to implement it as a table header, it's the easiest way to flow the image above the content. These detail touches are where you really learn the nooks and crannies of the framework.
