Learn how to implement data sharing in an app group. Understanding how to implement the code for data sharing is necessary.
- [Instructor] So now that we've set the app group … for our app to group dot com dot some site dot sharing … we can share date between the two using user default. … So let's look at that and notice that our other target … also has that same app group. … Also notice I had to change my bundle identifiers. … Having some provisioning issues. … I'm sure you've probably never run into that. … But I'm also sure your bundle identifier is not … the same as mine. … Okay, so let's look in the master view controller. … And up at the top after the view did appear … I'm going to add some more test code here. … So the first thing I'm going to do is I'm going to do a guard … let UD equal user defaults. … And I'm going to use the initializer that takes a suite name. … Now, this name we put in here is the same … as our app group name. … So for us it's going to be group dot com dot … some site dot sharing. … And now we should have the user defaults that we can get … data from and put data to to share between our two apps. …
