I was expecting to find that in the NSAttributeDescription class, but only the default value is there.

Behind the scene I tought a validationPredicate was created but trying to reach it using

    NSDictionary* dico= [[myManagedObject entity] propertiesByName];
NSAttributeDescription* attributeDescription=[dico objectForKey:attributeKey];
for (NSString* string in [attributeDescription  validationWarnings])

just get me nowhere, no validationWarnings, no validationPredicates...

any thoughts on this ?

Edit1: It seems that getting the entity straight from the managedObject doesn't give you the full picture. Getting the Entity from the NSManagedObjectModel permits to reach the validationWarnings & validationPredicates...

I'm a complete newbie when it comes to iOS programming and much less Core Data.
