Build a Playlist Browser

Keeping it short, I had some mac issues and lost all of my apps. I downloaded the Build a Playlist Browser files and allowed Xcode to make the updates to it. All but one error were fixed. Does anybody know what to do about this? It's in the PlaylistMasterViewController. It says 'find' is unavailable: call the indexOf() method of collection.

import UIKit

class PlaylistMasterViewController: UIViewController {

var playlistsArray: [UIImageView] = []
@IBOutlet weak var playlistImageView0: UIImageView!
@IBOutlet weak var playlistImageView1: UIImageView!
@IBOutlet weak var playlistImageView2: UIImageView!
@IBOutlet weak var playlistImageView3: UIImageView!
@IBOutlet weak var playlistImageView4: UIImageView!
@IBOutlet weak var playlistImageView5: UIImageView!

override func viewDidLoad() {

    playlistsArray += [playlistImageView0, playlistImageView1, playlistImageView2, playlistImageView3, playlistImageView4, playlistImageView5]

    for index in 0..<playlistsArray.count {
        let playlist = Playlist(index: index)
        let playlistImageView = playlistsArray[index]

        playlistImageView.image = playlist.icon
        playlistImageView.backgroundColor = playlist.backgroundColor

override func didReceiveMemoryWarning() {
    // Dispose of any resources that can be recreated.

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
    if segue.identifier == "showPlaylistDetailSegue" {

        let playlistImageView = sender!.view as! UIImageView
        if let index = find(playlistsArray, playlistImageView) {
            let playlistDetailController = segue.destinationViewController as! PlaylistDetailViewController
            playlistDetailController.playlist = Playlist(index: index)


@IBAction func showPlaylistDetail(sender: AnyObject) {
    performSegueWithIdentifier("showPlaylistDetailSegue", sender: sender)

Never mind I wasn't putting playlistArray before indexOf.
