# reverseObjectEnumerator() Returns an enumerator object that lets you access each object in the array, in reverse order. ``` func reverseObjectEnumerator() -> NSEnumerator ``` ## Return Value An enumerator object that lets you access each object in the array, in order, from the element at the highest index down to the element at index `0`. ## Discussion When you use this method with mutable subclasses of `NSArray`, you must not modify the array during enumeration. It is more efficient to use the fast enumeration protocol (see [`NSFastEnumeration`](/documentation/Foundation/NSFastEnumeration)). Fast enumeration is available in macOS 10.5 and later and iOS 2.0 and later. ## See Also [`- nextObject`](/documentation/Foundation/NSEnumerator/nextObject()) Returns the next object from the collection being enumerated. --- Copyright © 2026 Apple Inc.
