NSPredicate - filtering values based on a BOOLEAN stored value

Question

I have a core data model object called Entry. In this I have an attribute IsFavorite.

I would like to use an NSPredicate to filter the results of my NSFetchedResultsCont

Answer 1

For me, on SWIFT 3.0 use NSNumber and %@ didn't work, I had to use integer values:

NSPredicate(format: "yourAttributeName == %i", yourBooleanValue ? 1 : 0)

Answer 2

For me it worked like this

NSPredicate *predicate = [NSPredicate predicateWithFormat:@"(isComplete LIKE[c] %@)",[NSString stringWithFormat:@"%@",[NSNumber numberWithBool:YES]]];
