Project Feedback!

Looks good, this exercise is intended in part to give you an introduction to the general rhythm of this course. The course is entirely project-based with an app being assigned each week and then due the following week. Each project builds on the last to help each engineer learn the practical elements of iOS development and best practices as quickly as possible. We also do a code review for each submitted project once the program begins.

The next step is to continue working on [optional features](https://courses.codepath.org/snippets/ios_university/prework.md#heading-5-optional-add-a-settings-screen-to-the-tip-calculator) and [extending](https://courses.codepath.org/snippets/ios_university/prework.md#heading-6-optional-extend-your-app-improve-ui-add-features) your tip calculator. With regards to extensions to implement, we are looking for developers with an interest in user experience and product development so be sure to focus on additional functional enhancements and/or improving the user interface of the app.

We have a detailed [Prework Feedback Guide](http://courses.codepath.org/snippets/ios_university/feedback_guides/prework_feedback.md) which gives a high-level overview of the concepts covered in the project. Take a moment to go through the Swift 3 style guides and tweak your project to conform to these style conventions.

Start by reading the linked optional-features and Prework Feedback Guide pages, then review the Swift 3 style guides. Choose a specific functional enhancement or UI improvement for the tip calculator, including the optional settings screen, and confirm the app conforms to the stated style conventions.
