# last(where:) Returns the last element of the sequence that satisfies the given predicate. ``` func last(where predicate: (Self.Element) throws -> Bool) rethrows -> Self.Element? ``` ## Parameters `predicate` A closure that takes an element of the sequence as its argument and returns a Boolean value indicating whether the element is a match. ## Return Value The last element of the sequence that satisfies `predicate`, or `nil` if there is no element that satisfies `predicate`. ## Discussion This example uses the `last(where:)` method to find the last negative number in an array of integers: ``` let numbers = [3, 7, 4, -2, 9, -6, 10, 1] if let lastNegative = numbers.last(where: { $0 < 0 }) { print("The last negative number is \(lastNegative).") } // Prints "The last negative number is -6." ``` > Complexity: O(*n*), where *n* is the length of the collection. --- Copyright © 2026 Apple Inc.
