Instance MethodSwift


    Returns the last element of the sequence that satisfies the given predicate.

    func last(where predicate: (Self.Element) throws -> Bool) rethrows -> Self.Element?



    A closure that takes an element of the sequence as its argument and returns a Boolean value indicating whether the element is a match.


    The last element of the sequence that satisfies predicate, or nil if there is no element that satisfies predicate.


    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."
