Type safe JSON in Swift with SwiftyJSONModel

Table of contents

1. JSON everywhere
2. How would Apple do it?
3. Problems with Apple's approach
4. Using enum to store all the strings
5. Using SwiftyJSON to remove boilerplate

Step 1 - Make a Discord Webhook

1. Find the Discord channel in which you would like to send commits and other updates
