Dear TS200010,

Thanks for your report, and thanks for using the app. I did reproduce the problem, opening your file.

Now, looking at your file, it seems to me that :

StudyItem/flashCardSet relationship has an inverse relation that is set to StudyItem (the same Entity) and no inverse.
FlashCardSet/studyItems relationship has an inverse relation that is set to FlashCardSet (the same Entity) and no inverse. (see diagrams)

So, for me, the diagram correctly represents the model... If you want an arrow between those, you need to set the inverse of one of them to be the other (both entity and relationship).

Do you agree or is there something I missed ?

Many thanks !

That would explain what appeared to me to be an error. Thanks for taking the time to look at it.

I have also just spent an hour rebuilding the xcdatamodel (no d) file as it suddenly stopped compiling after I think I saved it in error. The offending line was
<attribute name="answer" optional="YES" attributeType="String" defaultValueString=""""/> and its the four quotes causing the problem. Xcode puts &quot &quot not "" if that is what I enter as a default string.

I cannot be sure that they originated with your software but I mention it just win case.

Many thanks.

I will have a look at this 4 quotes story, it may come from the app indeed. But it’s now 8 am in my time zone, I am on the bus to go to work. I’ll look at it tonight 😀 Thanks again.
