App group data sharing

- [Narrator] Another way to share data between apps … is by using app groups, so let's look at that. … I'm going to go back to my Signing & Capabilities tab … and add under Capability, App Groups. … Now I was playing around with this before … so I already have some default ones. … I'm going to add this app to this group.com.somesite.sharing. … That one was already defined, … but if you want to create a new one, … you press the plus button … and then you give it a unique name. … It has to be unique 'cause that's how it's validated. … Now, once you create this, … you can share user defaults … and you can also share some file storage. … It also creates a keychain access group. … You don't see it in the list, … but you can use the same text without the team ID … and use that as your keychain access group … when you're storing items … and you'd see it in the keychain database, as well. … So this one kills two birds with one stone. … You could remove this keychain access group … and just use this same text instead …
