Lecture 13: Persistence

The penultimate lecture of Stanford’s Spring 2020 iOS development course covers more ways to store data, including in iCloud via CloudKit and into the iOS device’s own filesystem. CloudKit is a mechanism for storing the user’s data in the cloud so that it will appear on all of their devices. The relevant data types are discussed as well as the basics of its API for creating records, querying them, and interacting with them in your code. While there was not time to demo CloudKit this quarter, we do demo accessing the filesystem in this lecture by enhancing EmojiArt to store its documents there.
