This app converts your Apple iOS device into a Swift Calc App.
This is a simple basic calculator app you could use on your iOS device. All a user needs to do is just click on the 'Swift Calc' icon and they are taken right into the app. The first thing you see is a dark grey background. Then on top is your calculator digit window where the numbers pressed will be displayed. Right below is your key pad with its basic calculator options, Keys from 0-9, math operators +, -, *, / with an equal key and a 'C' key which clears the display.
