While working on automatic Core Data migrations for ScoreMo, I ended up running into merging issues that didn’t seem to make sense to me. Fortunately, Jeff LaMarche helped out with this useful article that resolved my issues. I guess that will teach me to skip learning material and assuming I can easily adapt what I need to from a stock project. At least it wasn’t as big of a pain as trying to add core data to my non-Core Data app in the first place. Thanks Jeff!
