As we mentioned, the most common frameworks for backend web development are Node.js, Rails, Django, J2EE, and .NET. While the details of the frameworks vary, they all share similar structures. For prototypes, Parse and Firebase are great options for quickly getting a functional backend, and we prefer Parse because it's open source and more in your control. If you build your iOS using Parse initially, it's easy to move it to a Node/Rails/Django/etc backend later. Reflecting on this project, you should make you understand:

• User registration and authentication
• Creating objects
• Constructing a basic query

Hopefully, you're beginning to see how you can assemble the things you've learned from the projects to build an app that you design yourself. Here are a few new concepts that we learned from this project that you should reflect on:

• Persisting the logged in user and logging out by programatically instantiating a view controller from the Storyboard and setting the window's root view controller.
• Working with sections and rows in a table view.
• Handling the selection of a row in a table view.
• Adding an array of related Parse objects (comments) to another Parse object (post).
• Integrating MessageInputBar, a custom input accessory.

From here on out there are no more assignments as the focus shifts to the final group project. You'll be working over the next several weeks to build your app idea with your team and then finishing the class with a demo day!
