About The Project

Calcu is a simple calculator app with basic memory capabilities. You can also use Calcu to calculate appropriate tips for waiters.

This Project is for my Term 4 elective, Native iOS Development 304, for which we were tasked to create a basic calculator application with memory functionality.

Built With

This iOS application was build using:

• Xcode as IDE
• Swift as Language

Installation

1. Download and Install Xcode https://developer.apple.com/xcode/ from the App Store (Only available on MacOS)
2. Clone the repo

git clone https:://github.com/ArmandPretorius/calcu.git

3. Then open the project in Xcode

Features

Basic Calculator Abilities

Memory log

Tip Calculation

Usage

When opening Calcu, you can calculate basic calculations like adding, subtracting, multiplying and dividing.

Next to the equal sign is a tip button, which gives you three options when clicked on. You can then add 10%, 15% or 20% to your total bill to tip your waiter appropriately.

You can save the answer to your memory, recall the memory, add and subtract from the memory and also clear the memory.

When clicking on the answers, you get presented with the history/log of all your previous calculations. At the bottom you can clear the log.

Logic

The application uses NSExpressions to make the calculations The application uses UserDefaults to save the calculation log and memory.

Challenges

• I would like to make it possible to select a log and use it for the next calculation.
• I'd also like to add an AC ability.
• I'd also like to add more gesture based interactions.
