showPlaylistDetail method doesn't work

I have coded the showPlaylistDetail method up and added the gesture recognizer to the PlaylistMasterViewController, but have not been able to get it to move to the PlaylistDetailViewController. Nothing happens. Have checked all my connections, and nothing seems to be out of place. What's wrong?

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

I posted the question, and found a typo and changed the spelling of the segue to: "showPlaylistDetailSegue" and checked the identifier to see if the ID matched. There was no error there, and the segue still does not work, so it is not a spelling issue.

Here is the code from PlaylistMasterViewController; thank you.

import UIKit

class PlaylistMasterViewController: UIViewController {

@IBOutlet weak var playlistImageView0: UIImageView!

override func viewDidLoad() {
    super.viewDidLoad()


    let playlist = Playlist(index: 0)
    playlistImageView0.image = playlist.icon
}

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 playlistDetailController = segue.destinationViewController as! PlaylistDetailViewController
        playlistDetailController.playlist = Playlist(index: 0)
    }
}

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

}

I think you got t the concept of how prepareForsegue works WRONG .. For example lets say we have an array of items that are display on a UITableview controller, Then if you tapped onto a row, it should take you into a new UIViewcontroller which will display in full detail for that specific row. This is how prepare segue happened you don't need no @IBACtion. hope that helps

Thank you.

I deleted the whole method, and the tap recognizer, and than put them back in, and connected the tap recognizer, and ran a println() in the method and it worked. Not sure exactly why it worked, but it did. Now, I think I have the concept; thank you for explaining.
