Hi Wentai,

This is a great app! However, in it's present form, it would not quite qualify you for admission into the class. Due to limited space, we had to deny quite a few students who did really nice projects and even implemented several optional features.

With your present submission, I can offer you access to the class as an observer where you will have access to all the course material, but not be in the actual class.

In order to join the actual class, you would need to complete at least 2 more of the optional features. Unfortunately, with the next pre-work for the class being assigned tomorrow and the first class on Tuesday, you would need to submit any revisions by tomorrow morning 10am PST.

Please comment to this issue with how you wish to proceed. Charlie Hieger CodePath University Dean

Also, please confirm the University you attend.

Thanks Wentai!

This pre-work is a preview of our weekly project process. Generally, weekly projects take about 5 hours to complete the required features and an additional 5 hours to complete the optional features. In general, we've seen that the more hours you log, the quicker you improve your proficiency with iOS.

The purpose of this project was to begin to explore Xcode and to get a broad overview of iOS development using Swift. For example, in this project, we explored the following concepts:

Code styling in Swift. You can find some code styling guides here:

• Views are created in Storyboard, Interface Builder, or programmatically, but they have the same goal: instantiate, initialize, and layout view objects. We use IBOutlets to give names to view objects, similar to giving unique ids to divs in HTML.
• We registered for touch events, which can be done programmatically or via IBActions.
• We explored NSUserDefaults, one of the four persistence strategies in iOS.
• View controllers have a set of methods that are called when it loads, appears, or disappears. These are called view controller lifecycle methods.

Do your views look good on iPhone 4, 5, and 6? We will cover in class how to use Auto Layout to robustly design your views for different screen sizes and OS versions.

After this assignment, you should understand the purpose of IBOutlets and IBActions as well as the basics of designing views and programmatically interacting with the views from the controller.
