Can't play file from documents in AVAudioPlayer

I have a file on documents folder of app and I want to play it. 

if NSFileManager.defaultManager().fileExistsAtPath(pathString) {
    let url = NSURL(fileURLWithPath:pathString, isDirectory: false)
    do {
        let player = try AVAudioPlayer(contentsOfURL:url)
        player.prepareToPlay()
        player.play()
    }
    catch let error as NSException {
        print(error)
    }
    catch {}
}

There is a file on file system and I checked its existence. Also all lines in do block are executed. There is neither exception nor error and still no sound is played. What are possible problems and how can I solve them?

You should make audioPlayer an instance variable global. This code will have it deallocated immediately after calling .play() 

class ViewController: UIViewController {

    var audioPlayer = AVAudioPlayer()

    override func viewDidLoad() {
        super.viewDidLoad()

        if NSFileManager.defaultManager().fileExistsAtPath(pathString){
        let url = NSURL(fileURLWithPath:pathString, isDirectory: false)
        AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback, error: nil)
        AVAudioSession.sharedInstance().setActive(true, error: nil)

        var error:NSError?
        audioPlayer = AVAudioPlayer(contentsOfURL: url, error: &error)
        audioPlayer.prepareToPlay()
        audioPlayer.play()
    }
}
}
