Your code has some structural problems. I've cleaned it up a bit for you:

class ViewController: UIViewController {

    var audioSession = AVAudioSession.sharedInstance() // we only need to instantiate this once
    var player : AVAudioPlayer? // making this a property means player doesn't get released as soon as playSomething exits

    @IBAction func playSomething(sender: UIButton!)
    {
        if let ringURl = Bundle.main.url(forResource: "ring", withExtension: "m4r")
        {
            do {
                try audioSession.setCategory(AVAudioSessionCategorySoloAmbient)
                try audioSession.overrideOutputAudioPort(.speaker)
            } catch let error as NSError {
                print("audioSession error: \(error.localizedDescription)")
            }

            do {
                let ourPlayer = try AVAudioPlayer(contentsOf: ringURl)
                ourPlayer.prepareToPlay()
                ourPlayer.play()
                self.player = ourPlayer
            } catch let error as NSError {
                print(error.description)
            }
        }
    }

If you're still seeing a "-50" error, make sure your .m4r file is being included in your built application. I was just looking at a related question regarding this a few minutes ago, so the answers there might help you too.
