[Pre-work] Tip Calculator - Review my app: Just The Tippr

[jayliew]

My app is complete, please review. This is the minimum pre-work required to be eligible; I'll make it prettier over the next few days and tag you in follow up issues accordingly. Just wanted to send this now so that I can make it into the class! :)

Good work. This prework is a preview of our weekly project process. Generally, weekly projects take between 5-10 hours to complete the required features and an additional 5-10 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:
  • Ray Wenderlich Swift Style Guide
  • Github Swift Style Guide
• Views are created in Storyboard, Interface Builder, or programatically, 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 programatically 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? Do your views look good on both iOS 6 vs iOS 7/8? 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.

I apologize for the delay in reviewing your submission. You'll receive an email in the next day or so if you will have a seat in the class.

Hi @timothy1ee ,

I've added some animation, specific locale currency and thousands separator, calculated the amount if split for 2 and 3 people too. I also added an app icon.

In the "excellent" past submission shown, I couldn't figure out how the guy was able to show the pound sterling symbol.

Looking forward to meeting you on Monday! -Jay

Hi @codepathreview @timothy1ee ,

I'm not sure if the pre-work deadline is 9/23 or EOM, so I'm submitting now just to be safe. I'm traveling abroad with poor internet, but will be back in the Bay Area early next week! Please let me know if this will be a problem with the interviews .. I might be able to do a skype video chat call or something.

Great work!! 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.

Great to see you were able to complete a large number of optional features to your app already. Your project looks great. As you can probably tell, the optional features available on each project are a great vehicle for exploring the iOS framework deeper.

We'll be following up with you again shortly to outline the next steps in the admissions process.
