Submitted by: Zheng Hao Tang
Time spent: 6 hours spent in total
The following required functionality is complete:
- User can enter a bill amount, choose a tip percentage, and see the tip and total values.
The following optional features are implemented:
- Settings page to change the default tip percentage.
- UI animations
- Remembering the bill amount across app restarts (if <10mins)
- Using locale-specific currency and currency thousands separators.
- Making sure the keyboard is always visible and the bill amount is always the first responder. This way the user doesn't have to tap anywhere to use this app. Just launch the app and start typing.
The following additional features are implemented:
- List anything else that you can get done to improve the app functionality!
Here's a walkthrough of implemented user stories:

Describe any challenges encountered while building the app. As I do not have many programming experience, building this calculator is a difficult but fun experience. As first I have trouble learning how Xcode and swift work on building an application as it is unlike Java that I learned before. Instead of plainly writing code we can press CTRL keys and link the user interface to the swift code. It is a foreign environment to me for the way of building an application as we can simply adjust the user interface by creating shapes. Overall writing an IOS application is fun and I am looking forward to learn more of it.
