# filtered(using:) Evaluates a given predicate against each object in the receiving set and returns a new set containing the objects for which the predicate returns true. ``` func filtered(using predicate: NSPredicate) -> Set ``` ## Parameters `predicate` A predicate. ## Return Value A new set containing the objects in the receiving set for which `predicate` returns true. ## Discussion The following example illustrates the use of this method. ```objc NSSet *sourceSet = [NSSet setWithObjects:@"One", @"Two", @"Three", @"Four", nil]; NSPredicate *predicate = [NSPredicate predicateWithFormat:@"SELF beginswith 'T'"]; NSSet *filteredSet = [sourceSet filteredSetUsingPredicate:predicate]; // filteredSet contains (Two, Three) ``` --- Copyright © 2026 Apple Inc.
