CFCAppDemo (Or Carbon Footprint Calculator app demo)

This is a demo mobile application written in SwiftUI in which the user can select an origin and a destination airport, and calculate the carbon footprint of taking a flight between the selected airport.

🔧 Environment

📲 Prerequisites

In this demo, we took the approach to secure the secrets in the easiest, yet quite effective Apple’s way, using .plist file.

You are going to need your toohla api-key, which is used to get the flight offset data from their web services.

Once you get the API Key from toohla, please follow the below steps to secure the api key.

Step 1

Add a plist file at the root level of this project, and name it as you want.

In this demo, it is supposed to be API_KEY.

Step 2

Add your api key to the added API_KEY.plist file.

🎉🎉🎉 You are now all set.
