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
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
NSFast). Fast enumeration is available in macOS 10.5 and later and iOS 2.0 and later.
