Tipper is a tip calculator application for iOS.
Submitted by: Joshua Escribano
Time spent: 3 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.
- Settings page to change the default tip percentage.
The following optional features are implemented:
- UI animations
- Remembering the bill amount across app restarts (if <10mins)
- Using locale-specific currency.
- 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:
- Added light/dark modes changeable in the settings
Here's a walkthrough of implemented user stories:

Describe any challenges encountered while building the app:
- Mostly around how to set up the light/dark mode. I ended up settling on using a combination of protocols with some static class methods to change the current theme at a global level. It was also time consuming to add all the colors in code.
- Styling the back button on the UINavigationBar which I had to dive into title text attributes for (see SettingsViewController)
