NSPredicate: Filter multiple entity kinds

Posted bylantean 
let predicate = NSCompoundPredicate(orPredicateWithSubpredicates: [

    NSCompoundPredicate(andPredicateWithSubpredicates: [
        NSPredicate(format: "entity = %@", Note.entity()),
        NSPredicate(format: "content CONTAINS[cd] %@", "1")
    ]),
    
    NSCompoundPredicate(andPredicateWithSubpredicates: [
        NSPredicate(format: "entity = %@", Tag.entity()),
        NSPredicate(format: "name CONTAINS[c] %@", "tag")
    ])
])

Now, this yields another problem: there is no API to limit the number of entities to fetch “per group”.

If you do need this feature, you’re probably better of with multiple NSFetchRequest(s).
