Tip Calculator is a tip calculator application for iOS.
Submitted by: Adnaan Syed
Time spent: 10-12 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.
- User can select between tip percentages and the tip value is updated accordingly
The following optional features are implemented:
- 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:
- Implementation of a new navigation controller, with an additonal Settings View in the application
- Created a UISlider, allowing a user to pick a specific tip percentage, whose numeric form can be seen on a UILabel
- Created a UISegmentedControl, which allows users to split the bill up to 5 people.
- Added a UISwitch in the Settings View, which allows a user to use the application in Dark Mode or Light Mode
Here's a walkthrough of implemented user stories:
I did not have any prior experience with Swift, but I was familiar with similar languages, such as JavaScript and Python. The initial requirements were simple because of the guided instructions offered. Yet implementing the additional features was not as intuitive because I had to do my own research.
For the additional features, StackExchange, Swift blogs, and the official Apple "Develop in Swift: Fundamentals" helped alot with understanding how to use multiple views in one app and the different characterstics of different outlets.
This was overall a fun experience, which allowed me to create something functional and have fun with some UI/UX design.
