Welcome to saving data in iOS part two. This part will focus on JSON and the basics of the JSON format. You'll be starting off by decoding JSON, then you'll learn what goes into encoding it and why it's important. You'll also learn about Swift's Codable protocol for encoding and decoding. Let's jump right back into things before forgetful Felipe starts creeping back in and I forget what we learned in the previous part.
