@Catfish_Man thanks for this guide, David! Q: when I use NSUD as a message passing medium, my app perf drops. Can you make dispatch faster?

@steve_holt I suggest switching to IDS

@Catfish_Man 2nd Q: can NSUD be used as a replacement for associated objects in scenarios where the objc runtime doesn’t support them?

@steve_holt yes, this is what -setVolatileDomain:forName: is for

@Catfish_Man fantastic. Can that be persisted in the global domain?

@steve_holt if you delete your home directory, the global domain will go volatile (…not actually joking )

@Catfish_Man I wrote a subclass of NSIncrementalStore backed by NSUserDefaults. Should I throw myself into a volcano?

@Catfish_Man @bwebster I think that SO OFTEN about code. Imagine that Dr. Who "you're so beautiful" grin, followed by running for my life.

(Feedback welcome! Let me know if there's anything I can make clearer, or anything I forgot to cover)

@catfish_man great writeup! It implies that persistentDomainForName: is safe for getting a snapshot of (say) the Dock’s preferences, right?

@rbrockerhoff sure. It should be the same as [[[NSUserDefaults alloc] initWithSuiteName:@"com.apple.dock"] dictionaryRepresentation]

@Catfish_Man this is amazing, cheers

@hbkirb thanks :D

@Catfish_Man curious if you’d know: why are they “defaults”? why not “preferences” like the CF functions?
