NSUserDefaults.addSuiteNamed() having no effect

Vote count:

0

I created an app group to share preferences between an iOS app and an extension. From either app I can get a defaults instance and successfully read and write values like this:

let sharedDefaults = NSUserDefaults(suiteName: "group.com.example")
sharedDefaults.setObject("bar", forKey: "foo")
sharedDefaults.stringForKey("foo") // → "bar"

However, adding the group’s suite name to standardUserDefaults has no effect:

NSUserDefaults.standardUserDefaults().addSuiteNamed("group.com.example")
NSUserDefaults.standardUserDefaults().stringForKey("foo") // → nil

Am I misunderstanding something here?
