👍 Congratulations on finishing the final assignment! It's impressive to realize how far you've come in the class.

The point of this homework was to explore an example of a full MVC application with a RESTful API. We added this homework so that you'll have the experience building an app that's more similar in complexity to a production app.

We have a detailed Project 4 Feedback Guide which covers the best practices for implementing this assignment. Read through the feedback guide point-by-point to determine ways you might be able to improve your submission. You should consider going back and implementing these improvements as well. Keep in mind that one of the most important parts of iOS development is learning the correct patterns and conventions.

One immediate item - your app crashes if the user does not have a profile banner url. You're not checking for a nil value in the ProfileViewController and it causes the crash. You should always check for nil rather than force unwrap.

If you have any particular questions about the assignment or the feedback, feel free to reply here or email us at universitysupport@codepath.com.
