On a hopefully-not-overly-self-promotional tangent: If you're looking to debug - or just easily read - NSKeyedArchiver output, my 'YACYAML' NSKeyedArchiver implementation produces YAML output that's really easy to read (and write). It uses YAML 'anchors' to cope with deduplication similarly to MPWXmlArchiver. It's available at https://github.com/th-in-gs/YACYAML. It does, of course, come with the same security caveats that any NSArchiver subclass should come with, as already discussed. There is a "YACYAMLKeyedUnarchiverOptionDisallowInitWithCoder" option that you can use though, which restricts it to decoding YAML-native classes (sets , dictionaries, strings, arrays etc.).
