MPMovieViewController crashing with Swift

[gdroel]

Hi Cameron, just wanted to say that you've done a really nice job on this project! However, I'm having trouble with some Swift code. Whenever I call the MPMovieController, a black screen shows. Here is some code:

    func makeMovie(){

        let settings:NSDictionary = CEMovieMaker.videoSettingsWithCodec(AVVideoCodecH264, withWidth: images![0].size.width, andHeight: images![0].size.height)
        let movieMaker = CEMovieMaker(settings: settings as [NSObject : AnyObject])

        movieMaker.createMovieFromImages(self.images) { (fileURL:NSURL!) -> Void in

            self.viewMovieAtURL(fileURL)
        }
    }

    func viewMovieAtURL(fileURL:NSURL){
        var moviePlayer : MPMoviePlayerController?
        moviePlayer = MPMoviePlayerController(contentURL: fileURL)
        if let player = moviePlayer {
            player.view.frame = self.view.bounds
            player.prepareToPlay()
            player.scalingMode = .AspectFill
            self.view.addSubview(player.view)
        }
    }

I think it may be a problem with the fileURL, though no errors are being thrown. The MPMoviePlayer just shows a black screen. Thoughts?

Sorry about that, I just had to make MPMoviePlayer an instance variable.
