watchOS 2.0 & Core Data

Earlier I wrote about how I was able to give my watch app and my iOS app access to the same Core Data store and methods using a shared app group and a custom framework. Now, with watchOS 2.0, I’m going to have to rethink the whole system. The frustrating thing is, I don’t even know how to begin to go about doing that.

My Core Data store is tiny. The whole thing could sit happily on the Apple Watch itself without making a dent in anyone’s storage. So what…do I put one copy on the watch and one on the iPhone, and sync the changes?

I’m not sure why I’m having trouble wrapping my brain around this, but if you know how I should set up Core Data with my iOS app and a native watch application, feel free to contribute to my Stack Overflow question. I’d appreciate it!

EDIT: The answer is YES, I do need to maintain two separate stores. More on this later, when I get it all figured out.
