I'm testing the library and I have a problem with messagePassingDirectoryPath.
When I generate a message it's work correctly, but when I'm listening I have this issue:
I use listenForMessageWithIdentifier function to listen for messages and when in the library flow reaches messagePassingDirectoryPath function line:
NSURL *appGroupContainer = [self.fileManager containerURLForSecurityApplicationGroupIdentifier:self.applicationGroupIdentifier];
It always returns a null value.
the self.applicationGroupIdentifier variable has the correct value with my group.
If I set NSString *directoryPath = appGroupContainerPath; to a string with my actual path, something like (@"/Users/gero/Library/Developer/CoreSimulator/Devices/FA4C68DD-4F63-42B3-89A5-6C611A298199/data/Containers/Shared/AppGroup/B049FE4D-EE9F-44E3-AE2A-897C05447471/wormhole/) it works, and I receive messages correctly.
Do you know if it's an issue or I need configure something?
