How to use the “ALL” aggregate operation in a NSPredicate to filter a CoreData-based collection

Question

Based on the data model below

And based on user input I create a NSSet of managedObjects

Answer 1

This is the definite answer so far:

[NSPredicate predicateWithFormat:@"SUBQUERY(entryTags, $tag, $tag IN %@).@count = %d", selectedTags, [selectedTags count]];

B-E-A-U-T-I-F-U-L.
