Problem : Not working

P.S instead of PlaylistDetailController -> ViewControllerTwo

import UIKit

class ViewController: UIViewController {

    var playlistsArray: [UIImageView] = []

    @IBOutlet weak var playlistImageView0: UIImageView!

    override func viewDidLoad() {
            super.viewDidLoad()

        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() {
        super.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 = playlistsArray.indexOf(playlistImageView){
                let viewControllerTwo = segue.destinationViewController as! ViewControllerTwo
                viewControllerTwo.playList = PlayList(index:index)

            }
        }
    }


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


}

Andrey,

Try this:

import UIKit

class PlaylistMasterViewController: UIViewController {

    var playlistsArray: [UIImageView] = []
    @IBOutlet weak var playlistImageView0: UIImageView!


    override func viewDidLoad() {
        super.viewDidLoad()

        playlistsArray.append(playlistImageView0)

        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() {
        super.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 = playlistsArray.indexOf(playlistImageView) { //was find(playlistsArray, playlistImageView) {
                let playlistDetailController = segue.destinationViewController as! PlaylistDetailViewController
                playlistDetailController.playlist = Playlist(index: index)
            }


        }
    }

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

}

If this doesn't work, can you post what error you are getting?
