Array does not perform a command in swift [duplicate]

Question

Array does not perform a command in swift

I show a simple example

    var array = ["x", "y", "z"]
    var index = array.indexOf("y")

I get an error '[String]' does not have a member named 'indexOf'

I saw this question but it doesn't help me.

I imported

import UIKit
import Foundation
import AVFoundation
import CoreAudio
import MediaPlayer
import AVKit

what swift version you use? my guess is that indexOf method appeared in swift 2.0 — Vladimir
