Please review, @codepathreview

Kid is sick and I didn't have time to implement the optional stories.

Thanks Jim

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:

• Nice work encapsulating the properties into the private class extension for better encapsulation.
• 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.
• Nice work specifying the Auto Layout constraints.
• Nice work implementing the profile view controller so that it doesn't duplicate code in the timeline view controller.
• Nice work encapsulating the properties of the custom cells that you added.
• 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.

Congratulations on finishing the final assignment! It's impressive to realize that in just four weeks, you've gone from building a simple tip calculator app to a polished MVC client.
