You're trying to display your Pre-Roll Video Ad before your application has had any time to download it. Fire your moviePlayer.playPrerollAdWithCompletionHandler after a few seconds or move the video to a later point in your intro so your application has time to download the ad. Check my example:

import UIKit
import MediaPlayer
import iAd

class ViewController: UIViewController {
    // Create our MPMoviePlayerController
    var moviePlayer = MPMoviePlayerController()

    override func viewDidLoad() {
        super.viewDidLoad()

        // Preload ad
        MPMoviePlayerController.preparePrerollAds()

        // Setup our MPMoviePlayerController
        moviePlayer.view.frame = self.view.bounds
        moviePlayer.setFullscreen(true, animated: true)
    }

    @IBAction func playVideoButton(sender: AnyObject) {
        // Add our MPMoviePlayerController to our view
        self.view.addSubview(moviePlayer.view)

        // Path of video you want to play
        let videoURL = NSBundle.mainBundle().URLForResource("videoName", withExtension:"MOV")

        // Set the contents of our MPMoviePlayerController to our video path
        moviePlayer.contentURL = videoURL

        // Prepare our movie for playback
        moviePlayer.prepareToPlay()

        // Play our video with a prerolled ad
        moviePlayer.playPrerollAdWithCompletionHandler { (error) -> Void in
            if (error) != nil {
                NSLog("\(error)")
            }
            self.moviePlayer.play()
        }
    }

Tapping the UIButton playVideoButton a few seconds after application launch will play the prerolled video advertisement and then the desired video.

Also, If you're testing on your device go to Settings>Developer>Fill Rate> and make sure it is set to 100%.
