Join Bear Cahill for an in-depth discussion in this video Challenge: Add notes to keychain, part of Advanced iOS Development: Keychain Access.
(upbeat music) … - [Instructor] Okay, in this next challenge … we're going to add notes to the keychain. … Again, we're using the note struct, … which has text and a UUID. … The text is obviously the text of the note. … The UUID is the UUID, the universally unique ID. … Okay, so down here in the viewDidAppear, … we're checking to see if we have a detailViewController … and a selectedIndexPath. … This is if they're editing a note. … They've selected an idex path in the table view … and so they're editing. … This is where we're adding a new note, down here. … So in this part of the code, … this is where I want you to add the note to the keychain. … That's really all you have to do right here. … Most of the code is going to be in the secure manager … where you'll write new functions … for storing the note to the keychain. … And then later we'll look at how to fetch them and so on. … So I hope that makes sense. … Again, what you want to do is … only when they're adding a new note. … Use the UUID as the account for a generic password. …
