Would like to request more (any) info about how to solve problems. Happy day scenarios are nice and useful in case of complex systems such as CoreData, but there should be a chapter about various ways how CD would NOT work.
Rare cases, but very valuable when needed.
Right now I’m looking at my app to crash with Domain=NSCocoaErrorDomain Code=1560/1580 and finding nothing in the book. The rest of the error log (NSValidationErrorObject) tells me there’s something wrong with one of the relationships - and that’s the place where additional debug help would be useful.
Maybe there is something in the book, but I just can’t find it… Going back to Stackoverflow :)
