CNGroup can be encoded to data and that's it. Performing the reverse is not supported given name & identifier are read-only open properties hence decoding a data stream back to a CNGroup will always never work. Using the CNMutableGroup model will only give you the ability to encode and decode name in both directions but the super implementation of identifier will present the issue of only being able to encode the object to data and not the reverse.
