// How to:
// 1. Go in the Firebase Analytics Dashboard
// 2. Filter iOS Platform only
// 3. Scroll down, select `Device` under the "What is your audience like?" widget
// 4. Export the CSV data (top right of the corner, there's a `...` menu with Download CSV option)
// 5. Open the file and select the iOS breakdown raw data
// 6. Replace your data with the sample data in this script
// 7. Run the script in a Xcode Playground
// 8. See the terminal output
